Why Tungsten Heavy Alloy Is Adopted in Military Defense?
Nowadays, tungsten alloy is increasingly adopted as the raw material for military defens,and works as tungsten alloy military fitting, such as bullet, armor and shells, shrapnel head, grenade, bulletproof vehicles, tanks panzers, cannons, firearms, etc. Amajor tungsten alloy military fitting is in kinetic energy penetrators, where militarydefenses are in direct competition with depleted uranium (DU). Recent investigationsconducted at the Army Research Laboratory show that DU's superior properties resultedfrom its ability to localize shear during ballistic penetration events. Therefore, militarydefense was argued that if localized shear can be imparted to tungsten alloy, thesematerial would exhibit penetration performance matching that of depleted uranium(which had become an environmental problem).
You can image the subject envisions a penetrator, dropped from service height of a bomber aircraft, using kinetic energy to penetrate the shielding, and subsequently deliver a nuclear explosive to the buried target.
The problem with such a penetrator is the tremendous heat applied to the penetrator unit when striking the military defense shielding (surface) at hundreds of meters per second. Military defense has partially been solved by using metals such as tungsten (with a much higher melting point than steel), and altering the shape of the projectile (such as an olive). (You can get more information from http://en.wikipedia.org/wiki/Nuclear_bunker_buster)
During the World War Ⅱ, tungsten has already been used as an important raw material for military defense. There were abundant wolfram ore reserves found then in Portugal, which were used to produce tungsten concentrates for military defense.
Tungsten Heavy Alloy for Military Defense and Applications
In order to reduce the adoption of environmental hazardous materials in the military defense field, tungsten alloy military fitting is used as a non-toxic alternative for lead and depleted uranium in bullet and shot. High-density metals such as tungsten alloy military fitting is now widely employed; the goal of military defense is to create functional, high density, non-toxic arms projectiles with controlled impact behavior. The special properties of tungsten alloy make it almost ideal material for military defense applications.
Owing to its great hardness and resistance to high temperature, usage of tungsten alloy military fitting has been steadily increasing since the 1940's.

Tungsten for Defense
Advanced Hit Efficiency and Destruction
AHEAD is the acronym of "Advanced Hit Efficiency and Destruction". That AHEAD can also mean "ahead of …."， is indicative of the idea that AHEAD ammunition is a guided missile that is activated and deployed prior to reaching the target, "advancing interception". The core of AHEAD technology is made up of three parts, including AHEAD ammunition, muzzle velocity measurement, and timed detonator device/ data request system.
Below involve the pictures of a typical military application of tungsten alloy in the tungsten military defense (GDF-AHEAD, from Switzerland):

Technological Core of Tungsten Military Defense
The 35mm by 228mm AHEAD ammunition is an original cartridge type, programmed detonator ammunition, composed of a Programmable Fuze System, tungsten alloy subprojectiles, ejection standoff ammunition, a thin-walled body, nitrified fibre firing ammunition and steel ammunition cartridge. This tungsten military defense is become more and more widely used in the military field.
Tungsten Military Defense in Anti-missile:
In the anti-missile role it uses Advanced Hit Efficiency And Destruction (AHEAD) ammunition . This round ejects 152 tungsten projectiles at a predetermined distance, between 40 and 10 m, from the target. A 25-round burst of AHEAD rounds produces 3,800 of these small projectiles to destroy the incoming missile. Cruise missiles can be destroyed at 2.5 km and high speed missiles at 1.5 km range by tungsten military defense. A more common projectile to see in service is the advanced hit efficiency and destruction [AHEAD] round. Given the size of the diameter and the larger length of the projectile, as opposed to a 35mm AHEAD round, more subprojectiles are carried - one hundred and eighty as opposed to one hundred and fifty-two . The submunitions of this tungsten military defense are tungsten-alloy [WHA] spheres, designed for both penetration and 'mass effect', to increase the likelyhood of engaging the incoming 'vampire' or 'bogie'. The round is termed the MCP170 and uses a programmable magnetic fuze which uses information provided by the coil velocity gauge near the gun's muzzle in order to automatically compute the correct estimated time to target.
More knowledge of tungsten military defense for AHEAD C141:
The combat efficiency of the AHEAD ammunition is due to the payload of 152 tungsten alloy subprojectiles weighing 3.3 grams each. These subprojectiles are activated at a certain distance in front of the intercepted target, forming a mass of lethal subprojectiles, greatly augmenting the probability of a kill. The tungsten alloy subprojectiles have a sharp edge, ensuring that this tungsten military defense can inroad into the target with precise accuracy, tungsten military defense also provides the kinetic energy to destroy the electrical components, payloads or motor of the target.

Tungsten Alloy Defense Technology
Tungsten alloy defense technology in the area of thin-walled guided missiles allows bullets weighing 700 grams to hold 500 grams of effective load.The function of ejection stand off ammunition is to make a barrage out of the tungsten alloy defense, but not to markedly increase their kinetic energy. Nitrified fiber firing ammunition and a high intensity carbon steel ammunition cartridge endows the bullets with 1050metre/sec initial velocity.

Tungsten A l loy Swaging Rod Process ing
Brief Introduction of Tungsten Alloy Swaging Rod
Tungsten alloy swaging rod is made of tungsten alloy rod through calcinations. The normal method used in the processing are extruding, forging and sintering. After calcinations, tungsten alloy swaging rod has higher ductility, toughness and tensile strength than tungsten alloy rod, so it can be used for a longer time. Tungsten alloy swaging rod is widely used in industry as well as military areas, such as rifle bullet, armor piercing, snipe rifle penetrator, etc. Advantages of tungsten alloy swaging rod: low cost, easy operation, convenient processing adjustment and control, harder, more durable, excellent hardness (40HRC, tungsten alloy rod between 26HRC and
30HRC), high ultimate tensile strength (1200MPa~1400MPa), etc.
Tungsten Alloy Swaging Rod Processing:
Firstly, mix tungsten powder together with other elements, such as Ni, Fe, Cu, etc. Put them into a specially designed mold which is in heating furnace. Heat up to a certain temperature and through a certain time, we can get tungsten alloy rod.
Secondly, transfer the rod to a temporary support which supports the tungsten alloy rod is heated three quarters of an hour at about I600°C. In an electrically heated tube furnace, tungsten alloy rod is protected from oxidation at this temperature by hydrogen gas. Tungsten alloy rods are heated to about 1600°C. Then with an atmosphere of hydrogen gas in an electric furnace, tungsten alloy is rapidly passed through the swaging machine. In this operation the diameter of the rod is reduced 10 percent. Tungsten alloy rods are then re-heated in the furnace and are ready for the next pair of swaging dies which will again reduce its diameter by 10 percent.
Thirdly, machining. Tungsten alloy is so hard that it cannot be machined by sharp edge tools, but it can be brought into desire shapes by high temperature hammering or cold grinding.

What is Tungsten Alloy Armor Piercing?
Tungsten alloy armor piercing shell is a type of ammunition designed to penetrate armor. From the 1860s to 1950s, a major application of armor-piercing tungsten projectiles was to defeat the thick armor carried on many warships. From the 1920s onwards, armor-piercing weapons were required for anti-tank missions.
Tungsten Armor Piercing
Tungsten alloy armor piercing shell must withstand the shock of punching through armor plating. Shells designed for this purpose have a greatly strengthened case with an especially hardened and shaped nose, and a much smaller bursting charge. Some smaller-caliber AP shells have an inert filling, or incendiary charge in place of the HE bursting charge. The AP shell is now little used in naval warfare, as modern warships have little or no armor protection. The product remains the preferred round in tank warfare, as it has a greater "first-hit kill" probability than a high explosive anti-tank (HEAT) round, especially against a target with composite armor, and because of higher muzzle velocity, is also more accurate than a HEAT round. Tungsten alloy armor piercing cartridges are also available as small arms ammunition, primarily for use as an anti-materiel round.
Tungsten Alloy Armor Piercing Ammunition
Tungsten Alloy Armor Piercing
Tungsten alloy armor piercing ammunition is used to penetrate heavy hardened armored targets such as armored vehicles, concrete bunkers, tanks and other defenses. Depending on the caliber of the firearms. It is ammunition consists of a penetrator constructed of tungsten alloy or tungsten carbide, or depleted uranium, enclosed within a softer jacket, such as copper or aluminum. The product ammunition can range from rifle- and pistol-caliber rounds all the way up to tank rounds. Rifle and pistol rounds are usually built around a penetrator of hardened steel or tungsten. Aircraft and tank rounds sometimes use a tungsten alloy core. The penetrator is a pointed mass of high-density material that is designed to retain its shape and carry the maximum possible amount of energy as deeply as possible into the target. Depleted-uranium penetrators have the advantage of being hydrophobic and self-sharpening on impact, resulting in intense heat and energy focused on a minimal area of the target's armor. Some rounds also use explosive or incendiary tips to aid in the penetration of thicker armor. High Explosive Incendiary/Armor Piercing Ammunition combines a tungsten carbide penetrator with an incendiary and explosive tip.
Tungsten Alloy Armor Piercing
Rifle ammunition generally carries its hardened penetrator within a copper or cupronickel jacket, similar to the jacket that would surround lead in a conventional projectile. Upon impact on a hard target, the copper case is destroyed, but the penetrator continues its motion and penetrates the target. It's ammunition for pistols has also been developed and uses a design similar to the rifle ammunition. The entire projectile is not normally made of the same material as the penetrator because the physical characteristics that make a good penetrator (i.e. extremely tough, hard metal) make the material equally harmful to the barrel of the gun firing the cartridge.

What is Tungsten Alloy Cluster Munition
A tungsten alloy cluster munition , also known as a tungsten alloy cluster bomb, is a weapon containing multiple explosive submunitions. A cluster munition is a form of air-dropped or ground-launched explosive weapon that releases or ejects smaller submunitions. Commonly, this is a cluster bomb that ejects explosive bomblets that are designed to kill personnel and destroy vehicles.
Tungsten alloy cluster munition are defined and prohibited as a category of weapons. A tungsten alloy cluster munition is a form of air-dropped or ground-launched explosive weapon that releases or ejects smaller submunitions. Commonly, this is a cluster bomb that ejects explosive bomblets that are designed to kill personnel and destroy vehicles.
Tungsten alloy cluster munition roughly serve three purposes: firstly to defeat soft targets, i e personnel; secondly to defeat armoured of light armoured vehicles; thirdly to contribute to the suppressive effect, i e to avoid enemy forces to use their weapons without inflicting too much damage upon them.
Tungsten Alloy Swaging Rod for Cluster Munition
Tungsten alloy swaging rod is made of tungsten rod. The density, hardness and strength of tungsten alloy swaging rod is higher than tungsten alloy rod. Tungsten alloy swaging rod has been widely used for cluster munition.
Most cluster munitions contain shaped charge warheads which made by tungsten alloy swaging rod to pierce the armor of tanks and armored fighting vehicles.Tungsten allot swaging rod used for cluster bomb that ejects explosive bomblets that are designed to kill personnel and destroy vehicles or to destroy runways or electric power transmission lines, disperse chemical or biological weapons, or to scatter land mines. Some submunition-based weapons can disperse non-munitions, such as leaflets.
Tungsten alloy cluster munitions can penetrate many metres of reinforced concrete or rock in seconds. It is equipped with a detonator controlled by a computer that measures the density of the material passed through and, when the warhead reaches the targeted void or a set depth, detonates the warhead, which
then has an explosive and incendiary effect. The tungsten alloy burns fiercely and rapidly, carbonising everything in the void.

What is Tungsten Alloy Terminal sensitivity projectile
Tungsten alloy terminal-sensitive projectile is a kind of cluster bomb which contains a large number of smaller bombs and is very disruptive. It can be launched by cannons, long-range rockets or aircraft, and can automatically detect and recognize the targets and make accurate attacks, though it cannot continuously track the targets.
Tungsten alloy terminal sensitivity projectile is a kind of special cluster bomb projected by an aircraft or artillery. It has no guidance system, so it cannot automatically track the target as missiles guided by visible light, infrared light or millimeter wave. But, as anti-armor ammunition, it has the advantages of long attack distance, higher hit rate than conventional artillery shells and lower cost than missile. Therefore, it has broad application prospects in the fight against armored targets.
Tungsten alloy terminal-sensitive projectile is one kind of sensing instrument initiation cluster ammunition. With the increasing of the operational range, the damage efficiency of terminal-sensitive projectile was enhanced accordingly, but when the distance exceeds a certain range, it drops appreciably. The results can provide some helpful references for the overall design, and the system engineering method should be adapted to the index distribution, that will save the development period and budget.
Tungsten Alloy Swaging Rod for Terminal Sensitivity Projectile
Terminal-sensitive projectile is also called sensor-detonated projectile. The intelligent shell can detect the targets and turn the warhead toward them when it explodes.

The Theory of Tungsten Alloy Armor Piercing Bullets
Tungsten alloy armor piercing bullets are famous for their ability to penetrate target.It is mostly because large kinetic energy and their high tensile strength focused on the target. The bullets are made from the high-density tungsten alloy that is much harder than most armors. All have a very hard warheads.Tungsten alloy armor piercing bullets can be used against tanks, armored vehicles and concrete fortifications. When
fired, bullets are under the high-temperature, high-pressure gas. Reach the target, it will make a pit in the surface of the armor, red out the armor and the pit bottom at the same time. At this time, although the head has been broken, missile force the powerful impact of inertia, it will continue onrush. When the impact force reaches a certain value, the fuse is triggered, it caused the explosion of the projectile charge. At this time, exploding charge will create tons of pressure per square centimeter in area, killing the crew inside the tank or destroying armored weapons.
How does Tungsten Alloy Armor Piercing Bullets Work?
The most widely used tungsten alloy armor piercing bullets in the world are made of a hardened steel, tungsten alloy, tungsten-carbide, or depleted uranium penetrator enclosed within a softer material, such as copper or aluminum. Tungsten alloy rounds, for instance, take advantage of their high-density material, designed to retain its shape and carry the maximum possible amount of energy as deep as possible into the target. The tungsten alloy armor piercing bullets fired from rifles are strengthened with a copper orcuprous-nickel jacket, much like the jacket that surrounds lead in a conventional projectile, a jacket which is destroyed upon impact to allow the penetrating charge to continue its movement through the targeted substance. One of the most famous types of tungsten alloy armor piercing bullets used in the past was the Teflon-coated bullets. Contrary to popular belief, the Teflon coating did not in itself help the bullet penetrate deeper, instead it was meant to help reduce the wear on the barrel after firing hardened projectiles. The strange fact is that this misconception even produced laws that lead to the restricted use of these bullets, eventually leading to their extinction.
The famous example of such a blunder was the assassination attempt on US President Ronald Reagan that took place on March 30, 1981. Then, the shooter used an bullet with a normal revolver, which actually deprived the bullet of its ability, contributing to the bullet missing the heart by less than one inch and piercing his left lung instead, which likely spared his life. What most people do not realize, is that it is not enough to use tungsten alloy for armor piercing, you must use modified barrel, in order to take advantage of the bullet's piercing abilities.

What is Tungsten Armour Piercing Bullet?
Tungsten armour piercing bullet are specifically designed to penetrate steel and other metal armour. Tungsten Armour piercing bullet behave exactly like any other full-metal jacketed bullet until they impact hard steel armour. In fact standard Canadian Military rifle (C7) ammunition, with its SS109 bullet incorporates an armour piercing capability.
Armour piercing bullets are a specific design which incorporates a hard steel or tungsten penetrator inside the ammunition core. Only ammunition with this hard penetrator design is considered to be armour piercing. When the bullet impacts armour, it begins to flatten. As the nose flattens, the hard penetrator continues forward into the armoured surface while being supported by the bullet as it continues to flatten.
Tungsten Armor Piercing Bullet Advantages:
Tungsten Armour Piercing bullets do not explode, fragment or do any of the things you might see in a Hollywood movie. They are a simple kinetic energy penetrator. AP bullets are mainly found in military ammunition.
Tungsten armor piercing bullet has the properties of high initial velocity, low trajectory, short flying time, high accuracy, high penetration and more by adopting decorticating theory, new structure and material of tungsten heavy alloy:

Tungsten alloy is widely used in military field. It is one of the raw materials of small arms ammunition. It has many special properties. It has high density and high melting point, which is fit for military use. Compared to other materials, Tungsten alloy is non-toxic and environmental friendly. With high temperature resistance and low vapor pressure, it is also used in other field.
Tungsten alloy small arms ammunition will be available in its present form for the foreseeable future. Its function will continue to be to propel a projectile over a distance to strike a target. Variations in tungsten alloy and design of this ammunition will be in response to the specific needs of the many groups of small arms users.
The military will continue to develop tungsten alloy small arms ammunition which can penetrate and incapacitate a wide variety of targets ranging from humans to sophisticated electronic equipment. Currently, they are investigating "non-lethal" weapons and ammunition which will incapacitate a target without destroying it. Tungsten alloy small arms ammunition in this category include hand-held chemical lasers to knock out electronic sensors which are made by tungsten alloy, and foam guns which shoot sticky foam that envelops the target. These non-lethal devices would supplement, not replace, the conventional small arms weapons and ammunition.

Tungsten Penetrator Ammunit ion Components
Kinetic energy penetrators are currently relied upon as a way to defeat enemy armor. Historically these penetrators have been composed of unanium or tungsten based alloys due to their high densities. In addition to density, the deformation behavior of the alloy determines it's performance. A penetrator whose tip mushrooms or fractures on impact is less effective than a penetrator that retains it's shape or has a tip that self sharpens. Although the densities of uranium and tungsten are similar, uranium alloys have generally exhibited deformation on impact that has resulted in better penetrator performance. The drawback with uranium alloys, however, is toxicity and cost. In this Phase I SBIR program, tungsten alloys will be processed in a variety of novel ways to improve their performance as penetrators. The effect of rhenium additions will also be examined. X-ray diffraction, high rate compression testing, and optical microscopy will be used to assess the results.

Tungsten A l loy Ant i - tank Ammuni t ion
Tungsten alloy is important materials since they exhibit high density, comprehensive mechanical properties and good corrosion resistance, leading to many practical applications such as the part of the anti-tank Ammunition.For quite some time, a suitable replacement for the environmentally harmful depleted uranium (DU) for use as long rod penetrators has remained elusive. Tungsten based heavy alloys, commonly termed WHAs, with a tungsten grain size in the several tens ofmicrons, come close to the
performance of DU for Anti-tank Ammunition.
Following the First World War, tank armor was improved in terms of both thickness and quality. To be able to penetrate the armor of the tanks of potential enemies, it became necessary to design guns and shells for this specific purpose. During the thirties and fourties, a large number of new shell types saw combat. The descriptions below will give a brief overview of the main types of shells, explaining the basic designs, the method with which the shells penetrate an armor plate, and in which way they are designed to disable the tank against which they are fired.
Tungsten Alloy Anti-tank Ammunition Type
Armor Piercing, Discarding Sabot (APDS)
The principle of concentrating the kinetic energy of a large-caliber shell in a narrow penetrator is taken to the extreme with the armor piercing, discarding sabot (APDS) shell. Developed during the war, this shell type is similar to the APCR in penetration principle. Rather than fixing the outer shell to the penetrator, the outer shell, or sabot, is discarded from the penetrator immediately upon leaving the muzzle. The penetrator itself is a long, thin rod of a high-density material, such as Tungsten, or, after fission energy became common efter the war, depleted Uranium.
APDS shells offer very good penetration capability, but also suffer from the same issues as APCR shells. APDS also have the disadvantage that the sabot will impact the ground in front of the gun at a relatively high velocity, posing a risk to friendly troops.
Armor Piercing, Capped, Ballistic Cap (APCBC)
This shell type is a combination of the caps of the APC and the APBC shells.
Armor Piercing, Composite, Rigid (APCR)
The APCR round is also more likely to richochet, and the smaller small will cause less damage than a full-caliber shell, especially since the penetrator does not contain an explosive filler. Nevertheless, during the Second World War, it allowed the service life of low-caliber guns designed before the war to be extended.

Tungsten Alloy Swaging Rod Grades under Transient High Heat Loads
Transient high heat loads simulations by using the electron beam facility have been performed on two tungsten heavy alloy swaging rod grades at several power loads with a pulse duration of 5 ms. The cracking patterns of the two tungsten heavy alloy swaging rod grades are quite similar. All cracks occurred along the grain boundary and located across the loaded area. The cracks can be distinguished with two levels, major cracks with larger crack width but lower crack density and microcracks with smaller crack width but higher crack density. The higher the deformation level of tungsten alloy swaging rod for armor piercingand heat loading power density, the smaller the major crack density will be, but there is no obvious difference in the microcracks pattern. No melting occurred for both tungsten alloy swaging rod grades after transient heat loading at power density of 0.88 GW m−2.

Types of Tungsten Alloy Swaging Rod for Armor Piercing Projectile Introduction
Tungsten alloy swaging rod for armor piercing projectile which is made of tungsten alloy comprising a high density penetrator core with a tapered front end and a multi-part outer case in partial contact with the core. This kind of armor piercing projectile will not penetrate because the multi-part jointed case is not as strong as a single-piece, monolithic case. Also, since the hard core is loose and not bonded to the case, then the core can not provide additional structural support. In addition, tungsten alloy swaging rod for armor piercing projectile does not have the ability to either explosively damage the target after penetration, or take data from an instrumentation package during or after penetration. "Hollow-point" design results in radial expansion of the jacket into "petals" as the tungsten alloy swaging rod travels through the target. Such "flowering" of the case upon impact severely limits the depth of
penetration into hardened targets. Tungsten alloy swaging rod for armor piercing projectile comprising a heavy metal core and a segmented sabot with both right-handed and left-handed threads that separates from the core after exiting the gun's nozzle. It will not penetrate deeply because the nose end is made of a brittle heavy metal alloy, rather than high-strength steel. Also, it requires the use of a discarding sabot carrier. Tungsten alloy swaging rod for armor piercing projectile with a speculating core comprising an elongated arrow style it is of a core surrounded by a body, where the hardness of the core is greater than twice the hardness of the body. The outer case is made out of tungsten alloy swaging rod. The brittle behavior of these alloys will prevent this from achieving deep penetration in hardened targets, when compared to cases made of high-strength and high-toughness steel alloys.Tungsten alloy swaging rod for armor pierceing is our leader products. We can provide different sizes of it according as your requirements.

Tungsten A l loy Armor P lat ing
Tungsten alloy armor plating that protects the lower part of a door from kicks and scratches, covering the door to a height usually 39 inches (l meter) or more. Armor plate which was made by tungsten alloy, used as a sheathing for warships, tanks, and so forth to resist penetration and deformation from heavy gunfire.
Rifle and pistol rounds are usually built around a penetrator of hardened steel or tungsten. Aircraft and tank rounds sometimes use a core of depleted uranium. The penetrator is a pointed mass of high-density material that is designed to retain its shape and carry the maximum possible amount of energy as deeply as possible into the target. Depleted-uranium penetrators have the advantage of being pyrophoric and self-sharpening on impact, resulting in intense heat and energy focused on a minimal area of the target's armor. Some rounds also use explosive or incendiary tips to aid in the penetration of thicker armor. High Explosive Incendiary/Armor Piercing Ammunition combines a tungsten alloy penetrator with an incendiary and explosive tip.
When a weapon hits the armor plate and the weapon is powerful enough to break through, the block breaks apart. But the weapon looses its damage so the blocks behind may survive.
Tungsten alloy armor plating has a similar effect and through it is relatively light in comparison to the primary armor-plating of a vehicle, still has a detrimental effect on mobility and load-capacity. Being 50% lighter than aluminum cage armor and 85% lighter than steel cage options, tungsten alloy armor plating reduces the chance of overloading the vehicle and means that more equipment can be carried and further precautions taken to ensure the safety of the passengers.
Tungsten A l loy for Armor P ierc ing
Tungsten alloy is a kind of tungsten based alloy (tungsten quality fraction is usually 80% ~ 97%) which add Ni, F, Mn, Co, Cu, Mo, Cr or other metal elements its density is high as 16.5 ~ 19.0 g / cm3. Tungsten alloy not only has high density , it has a series of excellent properties, such as high strength, high hardness, good ductility, mechanical processing performance, small coefficient of thermal expansion , big coefficient of heat conductivity, resistance to oxidation and corrosion resistance, good weldability. Tungsten alloy has a wide range of applications in the advanced science and technology, military and civilian industry with its good properties.
One of tungsten alloy main application is tungsten alloy armor piercing. Tungsten alloy armor piercing has good performance of penetration. It also has the advantage of non-toxicity and non-radiation pollution, compared with depleted uranium (DU). Tungsten alloy is raw material for armor piercing around the world.
Tungsten alloy armor piercing utilizes tungsten based alloy which tungsten quality fraction is 90%~95%. It also adds Ni, Fe or other alloy ingredient. Tungsten content of few alloys is high as 98% or lower than 90%. This kind of tungsten based alloy which has high tungsten content has high density, highly improving penetration. It also has good resistance to compression and deformation, and means diameter can be decreased. With de decreasing of diameter, same force can be imposed on smaller area, highly improving the force on unit area and penetration of armor piercing.
At present, the usage of tungsten armor piercing in the world flows: In Israel, 0.87kg tungsten alloy is used for 60 projectile. 105mm rifle cannon uses tungsten alloy which has been processed by cold forging. In France, 60 mortar and 80 mortar are using tungsten alloy. 2.33kg tungsten alloy is used for 90mm rifle cannon and 3.78kg tungsten alloy is utilized for 105mm smoothbore gun. 120 smoothbore gun is adopting tungsten alloy which has the density of 18g/cm3.
Tungsten A l loy Penetrators
Tungsten penetrators, as well as steel alloy armor-piercing penetrators, must withstand the shock incurred while punching through armor plating. Penetrators designed for this purpose have a greatly strengthened case with an especially hardened and shaped nose. Tungsten alloy armor-piercing cartridges are also available as small arms ammunition, primarily for use as an anti-materiel round, for armored vehicles, concrete bunkers, tanks and other defenses, depending on the caliber of the firearms. This ammunition consists of a penetrator constructed of tungsten alloy or tungsten carbide, enclosed within a softer jacket, such as copper or aluminum. The product ammunition can range from rifle- and pistol-caliber rounds all the way up to tank rounds.
Kinetic Energy Penetrators
Kinetic energy penetrators — also known as long rod penetrators or LRPs — are a type of ammunition designed to penetrate vehicle armor. Much like a bullet penetrator, an LRP does not contain explosives and uses kinetic energy to penetrate the target.
The development of the modern kinetic energy penetrator combines two aspects of artillery design; high muzzle velocity and concentrated force. High muzzle velocity is achieved by using a projectile with a low mass and large base area in the gun barrel. Firing a small-caliber projectile wrapped in a lightweight outer shell — called a sabot —raises the muzzle velocity. Once the shell clears the barrel, the sabot is no longer needed and falls off in pieces. This leaves the projectile traveling at a high velocity with a smaller cross-sectional area and reduced aerodynamic drag during the flight to the target.
The High performance tungsten penetrate through corrosion for more stabilized readings with less effort.

Tungsten K inet ic Energy Penetrator
What is Tungsten Kinetic Energy Penetrator?
Tungsten kinetic energy penetrator (also known as a KE weapon) is a type of ammunition that, like a bullet, does not contain explosives and uses kinetic energy to penetrate the target.
The opposite technique to tungsten kinetic energy penetrator uses chemical energy penetrators. There are two types of these shells in use: high explosive anti-tank (HEAT) and high explosive squash head (HESH). They have been widely used against armor in the past and still have a role but are less effective against modern composite armor such as Chobham as used on main battle tanks today.
The principle of the tungsten kinetic energy penetrator is that it uses its kinetic energy, which is a function of mass and velocity, to force its way through armor. The modern KE weapon maximizes KE and minimizes the area over which it is delivered by:
being fired with a very high muzzle velocity
concentrating the force in a small impact area while still retaining a relatively large mass maximizing the mass of whatever (albeit small) volume is occupied by the projectile—that is, using the densest metals practical, which is one of the reasons depleted uranium is often used.
Tungsten kinetic energy penetrator has led to the current designs that resemble a long metal arrow.
Concentration of force into a smaller area was attained by replacing the single metal (usually steel) shot with a composite shot using two metals, a heavy core (based on tungsten) inside a lighter metal outer shell. These designs were known as Armour Piercing Composite Rigid (APCR). On impact, the core had a much more concentrated effect than plain metal shot of the same weight and size.
To maximize the amount of kinetic energy released on the target, the penetrator must be made of a dense material, such as tungsten carbide or depleted uranium (DU) alloy (Staballoy). The hardness of the penetrator is of less importance, but is still a factor as abrasion is a major component of the penetrator defeat mechanism.A common misconception is that, during impact, fractures along these bands cause the tip of the penetrator to continuously shed material, maintaining the tip's conical shape, whereas other materials such as unjacketed tungsten tend to deform into a less effective rounded profile, an effect called "mushrooming". Actually, the formation of adiabatic shear bands means that the sides of the "mushroom" tend to break away earlier, leading to a smaller head on impact, though it will still be significantly "mushroomed". Tests have shown that the hole bored by a DU projectile is of a narrower diameter than for a similar tungsten projectile.That is one of the reasons why tungsten kinetic energy penetrator is better than the DU it is.
Tungsten Prefabr icated Fragments
Fragmentation Damage Warhead's Mechanism and Characteristic
Fragmentation warhead is one of the main types of warheads, mainly by the role of high-energy explosives, the formation of a large number of high-speed fragments, using high-speed hitting the tungsten prefabricated fragments, the role of ignition and detonation damage targets, and can be used for anti-effectives (human, animal), no armor or light armored vehicles, aircraft, radar andmissiles and other weapons and equipment. According to the generation of fragments channels, fragmentation warhead can be divided into natural, pre-control and pre-fragmented warhead three types.
Tungsten prefabricated fragments are natural under detonation. Tungsten alloy ball, the shell expansion, fracture broken of such warheads is characterized not only as a container shell to form another anti-elements, fragments the size of the uneven, irregular shape in the air fast decay in flight speed, so that the effective anti-personnel grenade is limited in scope. Usually, tungsten prefabricated fragments made from tungsten alloy ball. We can provide different sizes of tungsten alloy balls in accordance with your requirements. Pre-control use of shell fragments groove, groove or increase the lining of explosives and other technical measures to make the shell partial reduction of the intensity to control the explosion of the broken parts to form fragments. Such warheads are characterized by the formation of uniform fragment size and shape. Tungsten alloy ball is one among our leading products.

Tungsten Cubes/Balls Used as Prefabricated Fragments
Primary fragments are formed as a result of the shattering of the casing of conventional munitions. Tungsten alloy frefabricated fragments usually are small and travel initially at velocities of the order of thousands of feet per second. Secondary tungsten alloy prefabricated fragments are formed as a result of high blast pressures on structural components and items in close proximity to the explosion. These prefabricated fragments are somewhat larger than primary fragments and travel initially at velocities in the order of hundreds of feet per second. A hazardous prefabricated fragment is one having an impact energy of 58 ft-lb (79 joules) or greater. Tungsten alloy refabricated fragments forming a pre-processing will be the shape and quality of pre-designed steel ball, steel arrows, tungsten ball/tungsten sphere, tungsten prefabricated column
fragments produced prefabricated sets of body fragments, and installed in the grenade projectile outer surface or inner surface. These prefabricated projectile fragmentation grenade explosion with the formation of fragments together constitute the natural fragmentation field, due to resistance of prefabricated fragments flying characteristic consistency, with tungsten alloy prefabricated fragments of the grenade will be set within the framework of the lethal effect of a relatively dense, full-bombs a greater degree of lethality increase.
Tungsten heavy alloys usually consist of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy also contain added cobalt (Co), etc., The most important property for tungsten alloy cube is its small volume and high density. The most important property for tungsten alloy cube is its small volume and high density. This allows it to be used whenever small but heavy parts are necessary, such as prefabricated fragments for military purposes.
Because prefabricated fragments will affect the negative effects of missile body structures, usually only in low-pressure chamber which uses artillery andammunition, such as the forced large-caliber bullets and grenades.

Tungsten A l loy Fragment
What Is Tungsten Alloy Fragment?
Tungsten alloy fragment can be used for military purposes.It control has included providing grooves on either the external or the internal surfaces of the wall of the case or a liner inserted into the case. The grooves create stress concentrations that cause the case to fracture along the grooves forming fragments. While these devices have demonstrated the ability to create it, they are not completely satisfactory for several reasons. It can be widely used in military defense.
One prior approach to inducing tungsten alloy fragmentation control to an integral warhead and missile structure has been to include grooves on either the external or internal wall surfaces of the structure to delineate fragments or projectiles in a combined warhead and missile structure. Explosives are installed in proximity to the grooves. When the explosives are detonated, the grooves create stress concentrations that cause the structure to fracture along the grooves, forming tungsten fragments.
Still another approach is the dual-wall naturally fragmenting (and combination natural fragmenting and scored wall) warhead. While these types of warheads have provided somewhat of an improvement over single-wall naturally fragmenting warheads, current dual-wall designs generally require thermal conditioning manufacturing methods to mate walls together with tight circumferential tolerances. We can provide different size tungsten alloy fragment according to your requirement, tungsten fragment is one of our leading products.
Tungsten Smal l Ca l iber Core
Why is Tungsten Small Caliber Core?
Tungsten alloy, also called tungsten for short, is used as a new lead-free small caliber core for national defense. Small caliber cores rages from 9mm to 0.50 caliber including 5.56mm, 7.62mm, 9mm, 0.38 and 0.45 caliber, etc., could be produced by tungsten mixtures metal with the same techniques used for the construction of lead-containing bullets but without any poison to environment. It is just as lethal as the standard core of 5.56mm without harming the environment. The day end the use of environmentally hazardous materials in small caliber cores for all ammunitions is coming.
Besides, as a high density metal, tungsten is mixed with the binder such as nickel, iron, copper, cobalt, etc. to produce the components with controlled density and mechanical properties. Powder metal mixtures such as tungsten small caliber core is simply cold pressed to produce a high-density material with superior properties, e.g. high hardness, good ultimate tensile strength, excellent elongation, etc.
Main Manufacture Process of Tungsten Small Caliber Core
Tungsten small caliber core is manufactured by powder metallurgy technique with some complex process. The main manufacture process is mixing, de-waxing, pressing, sintering, machining, and then move to surface control if there is a need, such as electroplating, engraving, etc. Heat treating is very necessary to achieve the appropriate properties for tungsten small caliber core, elongation would be improved by that process.
The combined processes of mechanical interlocking and "cold-welding" bond the metals together, and can be varied to control the properties of the non-lead core. Tungsten small caliber core can be pressed directly to shape, or cores can be produced that can be swaged into projectiles, with or without jacketing. So swaging is another important process for reaching a higher hardness at least 40HRC, meanwhile, ultimate tensile strength could be also increased to at least 1050Mpa. If the properties are needed higher, some of the processes would be adjusted.
Tungsten Small Caliber Core Properties:
The powder metallurgy approach has the potential not only to produce quality high density, non-toxic cores that are a direct replacement for lead, but also to revolutionize many of the aspects of core design and performance. Customerized tungsten small caliber core is warmly welcomed with high properties as follows: High hardness 40HRC min. (Regular tungsten material only about 28HRC) Excellent ultimate tensile strength 1050MPa min. (Regular tungsten material only about 900Mpa) Non-toxic to the environment Superior machinability
Tungsten Medium Ca l iber Core
Why is Tungsten Medium Caliber Core?
Tungsten heavy alloy, also called tungsten alloy for short, is used as a new medium caliber core for national defense, such cores are being fabricated from mixtures of powdered metals, and/or coated metal powders or particulates that are consolidated to form dense metallic materials. The primary goal of the project is the development of functional, high density, non-toxic small arms projectiles with controlled impact behavior, i.e. frangibility, for training and field use. Preliminary results have been achieved using cold pressed mixtures of metal powders. Therefore, a king of core materials with properties similar or superior to depleted uranium is badly needed to be fabricated and tested. Tungsten material should be a wonderful replacement.
Main Manufacture Process of Tungsten Medium Caliber Core
Tungsten medium caliber core is manufactured by powder metallurgy technique with some complex processes. The main manufacture process is mixing, de-waxing, pressing, sintering, machining, and then move to surface control if there is a need, such as electroplating, engraving, etc. Heat treating is very necessary to achieve the appropriate properties for tungsten medium caliber core, elongation would be improved by that process.
The powder metallurgy approach is that the composite core materials are completely recyclable. The binder and high-density metals are not chemically bound and the binder metal does not wet the dense constituent. The metals are easily reclaimed from the scrap collected at firing ranges employing simple heat treatments. This will provide a new and less expensive source of raw materials, inevitably lowering cost. Swaging is another important process for reaching a higher hardness at least 40HRC, meanwhile, ultimate tensile strength could be also increased to at least 1050Mpa. If the properties are needed higher, some of the processes would be adjusted.
Tungsten Medium Caliber Core Advantages:
Tungsten medium caliber core usually rages from 20 mm to 35 mm, used on navy vessels, helicopters, fighter aircraft and anti-aircraft cannons, as well as infantry fighting vehicles, also could used for high quality percussion caps of all types, as well as links for various small- and medium-caliber rounds. Guangxi Chentian Metal Products Co. Ltd could offer tungsten alloy fittings used as a part to tungsten medium caliber core with the following proerpties:
High hardness 40HRC min. (Regular tungsten material only about 28HRC) Excellent ultimate tensile strength 1050MPa min. (Regular tungsten material only about 900Mpa) Non-toxic to the environment (superior to depleted uranium core) Superior machinability

Medium and Large Caliber Ammunition
The medium and large calibre ammunition is derived from tungsten. This extremely dense, heavy metal is about 1.7 times heavier than lead, and far more difficult to deform than steel. It is excellent for use in armor-piercing. Because of tungsten's great properties and strength, it is very useful for piercing deep into synthetic, metallic targets.
Tungsten alloy armor-piercing medium and large caliber ammunition possess characteristics of compression resistance and non-tensile, when it penetrate armor, nearly no deformation occurred, and form fragment after punching through armor plates, increase killability and combustion effect, besides are more than armor-piercing made by other materials. The AP shell is now little used in naval warfare, as modern warships have little or no armor protection, but it remains the preferred round in tank warfare, as it has a greater "first-hit kill" probability than a high anti-tank (HEAT) round, especially against a target with composite armor, and because of higher muzzle velocity, is also more accurate than a HEAT round. Tungsten alloy medium and large caliber is used to penetrate hardened armored targets such as ballistic vests, vehicle armor, concrete, tanks, and other defenses, depending on the caliber of the firearms. Armor-piercing ammunition consists of a penetrator constructed of hardened steel, tungsten carbide, or depleted uranium, enclosed within a softer jacket, such as copper or aluminum.

Tungsten A l loy for Tank System
What is MBT-70 in Tank?
The MBT-70 (German: KPz 70) was a 1960s German-U.S. joint project to develop a new main battle tank, which was to be equipped with a number of advanced features. It utilized a newly developed hydropneumatic "kneeling" suspension and housed the entire crew in the large turret. The MBT-70 NBC system was armed with a 152 mm XM-150 gun/launcher, which could use conventional ammunition and the Shillelagh missile for long range combat. In 1969 the project was well over budget and the Germans withdrew from the effort, developing a new main battle tank on their own instead (the Leopard 2). In the US the development continued for a short time, until in 1971 the Congress cancelled the program. The MBT-70 is the "grandfather" of the Leopard 2 and the M1 Abrams, the current main battle tanks of both countries.
History of Tank System
During the 1960s the US Army continued to improve the M60 tank. However, unless a new tank was fielded there would be a large gap between US and Soviet tanks when the Soviets fielded their next generation tank system. The first try at the Super tank concept, the MBT 70 NBC system was a failure due to high costs. An early example of a codevelopment initiative is the MBT-70 [Main Battle Tank 1970s] program between West Germany and the United States. Thanks largely to the
support of then Defense Secretary Robert McNamara, agreement was reached in 1963 between the two nations to jointly develop a main battle tank. With cast homogeneous steel layered armor, the inner shell was overlaid with spaced high hardness homogeneous rolled armor steel. The US prototype was equipped with a 152mm gun launcher with an auto loader. Main battle tank was capable of firing AP/HE/WP rounds and the Shillelagh Missile. The main battle tank was to be a long-
barreled improved XM-150 variant of the XM-81 gun/launcher mounted on the M551 Sheridan and the M60a2 Patton. Main battle tank was a much more reliable weapon than the earlier variant, firing Sabot, HE, and Canister rounds in addition to the Shillelagh A/T Missile, but the earlier weapon's reputation was such that it was a lost cause from the start. Main battle tank had a coax 7.62 machinegun and a 20mm AA remote control gun in a separate part of the turret. Main battle tank would pop up out of twin hatches and fire at the target. The German version had a 120mm auto cannon, instead of the 152mm gun launcher. In some respects, the tank was fairly conventional. Main battle tank had a diesel engine, and the armor, whilst strong was not of the composite type on the Abrams. The silhouette was low. The main battle tank had a three-man crew, each in his own compartment. Probably the most intriguing aspect was that all the crewmen were located in the turret. The driver was in the turret, in a capsule that rotated to keep him orientated to the front of the vehicle. This had the effect of raising the silhouette a little, and if the contra-rotating mechanism was knocked out, it would effectively immobilize the tank. Main battle tank was to include hydro pneumatic suspension, stabilization system, and a NBC system. The hydro pneumatic suspension allowed the vehicle to crouch or raise one end of the tank to better take advantage of hull-down positions.
Tungsten Alloy for Tank System
Problems, however, plagued the MBT-70 NBC system program from the beginning. Difficulties with English-German translations, metric to English measurement conversions, and differences between German and American manufacturing and designing practices caused considerable headaches before the first tanks were even designed. Most of the new systems were still experimental and this led to massive cost overruns and delays. Also the joint nature of the program led to disagreements about design features. From 1965 to 1972, the US Army conducted a parallel development program for the 152mm XM578 cartridge, which was co-developed with the prototype MBT-70 Main Battle Tank. The XM578 cartridge used a tungsten alloy that was slightly denser than the British alloy, consisting of 97.5 percent tungsten and 2.5 percent binder, which had a density of 18.5 gm/cc. In response to the new operational requirements, military developers evaluated a succession of metal alloys. Initially, the British government developed a higher density tungsten alloy consisting of 93 percent tungsten and 7 percent binder tungsten alloy (WA). The new WA alloy had a density of 17 gm/cc -- versus 13 gm/cc for tungsten carbide.
Tungsten Alloy for Tank System-1 Tungsten Alloy for Tank System-2 Tungsten Alloy for Tank System-3
Unfortunately, rising costs and technical problems caused the partners to go their separate ways. Trials began in 1968 and problems resulted in further delays and cost overruns. By 1969 the vehicle cost 5
times what was projected and as a result Germany backed out of the project. The MBT-70 NBC system was finally halted in January 1970. The same fiscal year (1971-72) witnessed the termination of two major weapons procurement programs, one for the Cheyenne advanced attack helicopter and the other for the MBT-70 NBC system. Although Army leaders saw both weapons systems as critical to the Army's long overdue modernization program, they were unable to convince the Department of Defense and Congress of a need for these weapons commensurate with their costs. The joint effort with the Federal Republic of Germany, under which the MBT-70 NBC system had been developed, was modified to a co-operative program in the middle of Fiscal Year 1970. The US chose to give the MBT70 another chance, but this time as an austere vehicle with toned-down technological gizmos. This project was dubbed XM803, and it featured a less powerful engine, lacked the complex hydro pneumatic suspension, and was protected by a simpler armor array than MBT-70 NBC system. Changes in the US design were recommended to decrease production costs and increase the reliability of the vehicle; sacrifices in combat effectiveness were minimal. In December 1969, the new program was reviewed in the Office of the Secretary of Defense and in the following month the recommended changes were approved. With the modification of the program and of the co-operative features of the engineering effort, the tank received a new designation, XM803; the composite nomenclature MBT-70 / XM-803 was used until February 1971. The XM803, the successor to the abortive MBT-70 project, was intended to modernize the armored force. Concerned about expense, Congress withdrew funding for the XM803 in December 1971, thereby canceling the program, but agreed to leave the remaining surplus of $20 million in Army hands to continue conceptual studies. This resulted in the German Leopard II and the US M1 Abrams. The Leopard 2's power pack was originally designed for the German prototype of the MBT-70 NBC system. In 1973, cooperation between these two projects led to the adoption of the German 120mm smoothbore gun by the US.

Tungsten Alloy Properties
Tungsten alloy has so many good properties such as: high density (much higher than steel and 60% higher than lead), small volume, high temperature resistance, highcorrosion resistance, low vapor pressure perfect hardness (even harder than steel), non-toxic and environmentally friendly.
As the properties of tungsten alloy, tungsten alloy is widely used in making tungsten alloy flying carrier. Because of its great hardness and resistance to high temperature, usage of tungsten alloy applications has been steadily increasing since the 1940's. Tungsten alloy has high density with small capacity, so it is the best material to be used as counterweight; tungsten heavy alloy is the best choice to be used as counterweight. Compared with lead, tungsten has smaller volume, so tungsten's resistance is smaller than lead, which will make the carrier move ahead more quickly. Tungsten alloy carrier counterweights vary in size and shape.
Tungsten Alloy Flying Carrier
Tungsten alloy has the properties of wear resistance, excellent hardness, so the foot of flying carrier made of tungsten alloy material, when flying carrier flying and falling. Good corrosion resistance is one advantage for tungsten alloy to make flying carrier shoes, when the flying carrier emergency landing, it does have the choice of the ground, the tungsten flying carrier shoes can not be corrosion when the environment is bad.
When the flying carrier landing and sliding, the speed is so fast that the friction is so big and it can produce a lot of heat, flying carrier shoes can resistant this problems and keep the flying carrier land safely.

Tungsten Alloy Properties:
Tungsten alloy has so many properties such as: high density (60% higher than lead and much higher than steel), high radiation resistance, high temperature resistance, small volume, etc. As these properties, tungsten alloy is progressively adopted since the raw substance to create components of army products, which include bullet, armor and shells, shrapnel head, grenade, hunting gun, bullet warheads, bulletproof vehicles, tank panzers, cannons, firearms, tungsten alloy head shrapnel, etc. Head shrapnel relied almost entirely on the shrapnel velocity for head shrapnel lethality. The munition of head shrapnel has been obsolete since the end of World War I for anti-personnel use, when head shrapnel was superseded by high-explosive shells for that role. The functioning and principles behind head shrapnel shells are fundamentally different from high-explosive shell fragmentation. Tungsten alloy head shrapnel is anti-personnel artillery munitions which carried a large number of
individual bullets close to the target and then ejected them to allow head shrapnel to continue along the shell's trajectory and strike the target individually.
The high density of tungsten alloy ball makes it possible to significantly reduce the physical size of tungsten alloy head shrapnel components. This in turn, gives the benefit of greater control of weight distribution and increases the sensitivity of controlling mechanisms.

Tungsten APFSDS-Armor P ierc ing F in Stab i l i zed Discard ing Sabot
Tungsten Armor Piercing Fin Stabilized Discarding Sabot-Trace
Tungsten Armor Piercing Fin Stabilized Discarding Sabot-Trace(APFSDS-T) provides superior defeat capability over the M791 APFSDS-T round for the Bradley Fighting Vehicle. The long rod tungsten penetrator, of this highly effective anti-armor round, has excellent penetration characteristics with minimal dispersion. It is capable of defeating a wide array of target sets, including most modern armored infantry vehicles and armored personnel carriers
Tungsten Armor Piercing Fin Stabilized Discarding Sabot
Tungsten armor-piercing discarding sabot (APDS) was initially the main design of the kinetic energy (KE) penetrator. The logical progression was to make the shot longer and thinner to concentrate the kinetic energy in a smaller area.To maximize the amount of kinetic energy released on the target, the penetrator must be made of a dense material, such as tungsten alloy . The
hardness of the penetrator is of less importance, but is still a factor as abrasion is a major component of the penetrator defeat mechanism.
Tungsten armor piercing fin stabilized discarding sabot is significant standoff armor defeat capability, high reliability and high first round hit probability.
Significantly improved range and penetration over existing conventional APDS ammunition Features:
Higher muzzle velocity Significant increase in armor penetration Improved standoff range Barrel wear equivalent to other fielded U.S. Army 25mm ammunition Increased gun system life and reduced replacement costs Improved accuracy and lethality at long range These features greatly enhance light armored vehicles and armored fighting vehicles utilizing 25mm x 137 gun systems.

What is Tungsten Alloy Armor Piercing APFSDS?
Tungsten alloy armor piercing fin stabilized discarding sabot (APFSDS) is a type of ammunition which, like a bullet, does not contain explosives and uses kinetic energy to penetrate the target. The term can apply to any type of armor-piercing shot but typically refers to a modern type of armor piercing weapon, the tungsten alloy armo piercing fin stabilized discarding sabot, a type of long-rod penetrator (LRP), and not to small arms bullets.
The principle of tungsten alloy armor piercing is that it uses tungsten alloy armor piercing kinetic energy, which is a function of mass and velocity, to force its way through armor. The modern KE weapon maximizes KE and minimizes the area over which it is delivered by: maximizing the mass of whatever (albeit small) volume is occupied by the projectile—that is, using the densest metals practical, which is one of the reasons depleted uranium is often used, being fired with a very high muzzle velocity, concentrating the force in a small impact area while still retaining a relatively large mass.
Tungsten Alloy in Military Weapons:
Tungsten alloy has so many advantages: high density with small volume, high radiation resistance, non-toxic and environmentally friendly, excellent hardness, high melting point, etc. So it is widely used as the materials of military weapons such as tungsten alloy bullet, tungsten alloy armor and shells, tungsten alloy shrapnel head, tungsten alloy grenade, tungsten alloy hunting gun, tungsten alloy bullet warheads, tungsten alloy bulletproof vehicles, tungsten alloy tank panzers, tungsten alloy cannons, tungsten alloy
armor piercing, firearms, etc. Tungsten alloy can be used as the component in the kinetic energy penetrator .

Tungsten F in Stab i l i zed K inet ic Energy Penetrator Ammuni t ion
What is Tungsten Fin Stabilized Kinetic Energy Penetrator Ammunition?
A kinetic energy penetrator, which is also known as a KE weapon, is a type of ammunition, like a bullet. Armor piercing fin stabilized kinetic energy penetrator ammunition is a medium caliber round consisting of a fin stabilized long-rod solid penetrator. Fin stabilized kinetic energy penetrator ammunition is the most lethal kinetic energy ammunition, capable of destroying all known tank armour up to direct shooting range. Depleted uranium (DU) weapons are retained by around 20 countries worldwide, primarily as kinetic energy weapon, because it brings so many hazards to the environment. The study found that there is one type of new material related to tungsten is outstanding for ammunition with its high properties, it is a tungsten-based kinetic energy penetrators, which does not have the same political and environmental objections as DU rounds.
Why is Tungsten Fin Stabilized Kinetic Energy Penetrator Ammunition?
While DU doing bad to the environment, other penetrator materials such as chiefly different alloy of tungsten, are a comparable density to DU. Reason that DU is considered to be as effective as a penetrator material is that it combines high strength and density with a type of deformation on impact. However, tungsten material for tungsten fin stabilized kinetic energy penetrator ammunition has a much higher density, which rages from 17.0~18.5g/cm3. Mostly, tungsten content would be most popular at 93%W. Penetrator material is only one among many variables which determine the effectiveness of a kinetic energy round. Although DU appears to be the most effective material, some other materials such as tungsten has a better machinability, which is much easier machined than other material. Also in government documents from DU user states, they are discussing the changes to DU, are considering greater improvements in performance of fin stabilized kinetic energy penetrator ammunition.
Therefore, high properties tungsten fin stabilized kinetic energy penetrator ammunition are required badly for this case as the following advatages:
High hardness 40HRC min. (Regular tungsten material only about 28HRC) Excellent ultimate tensile strength 1050MPa min. (Regular tungsten material only about 900Mpa)
Non-toxic to the environment (superior to DU core) Superior machinability
Main Manufacture Process of Tungsten Fin Stabilized Kinetic Energy Penetrator Ammunition
A new type of tungsten that used in penetrator by powder metallurgy routes is welcomed by more and more countries for their national defense. The main matrix is some kinds of tungsten mixed powder added with some other metal powder, such as and also need to be mixed together with some other metal powders such as iron, copper, cobalt, nickel, etc. The other mental powders jus work as the binder to make sure the powder mixed equally. After mixing equally, then the mixture will be move into pressing process, to make it into the rod, brick, plate, tube ring, etc. Then the mixture will be moved into the high-temperature sintering process at least 1400 degree. Then the following steps such as heat treatment, swaging, annealing, etc. are all for make sure the tungsten part with qualified properties, such as hardness, elongation, etc.
Tungsten Ammuni t ion Core
What is Tungsten Ammunition Core?
Tungsten mixed with other metal powders such as nickel, copper, iron, etc. is a kind of suitable material for ammunition as its excellent properties such as high density, good ultimate tensile strength, wonderful machinability and environment-friendly. Ammunition such as semi-automatic ammunition and revolver ammunition could be used with tungsten material to improve its military properties, especially its high density, for semi-automatic ammunition, tungsten material could make it either rimless or semi-rimmed to facilitate feeding through the magazine. For revolver ammunition, though some revolvers can use rimless or semi-rimmed centerfire cartridges, generally rimmed. That is the so called tungsten ammunition core.
Why is Tungsten Ammunition Core But Not Lead Core?
Compared with lead core, depleted uranium, tungsten ammunition core do not adversely affect groundwater. Soil containing lead stunted the growth of rye grass, but the plant was unaffected by soil containing tungsten. Scientists also exposed earthworms to soil containing the two metals. Studies stated that there was no abnormal growth while using tungsten ammunition core, the reproductive patterns were the same. But in the lead-contaminated soil, the plants got smaller, and didn't have any offspring and died out. Therefore, that’s the most important factor to replace lead cores by tungsten ammunition core. The Army wants ammunition that is less likely to cause environmental damage, an alternative to lead-core ammunition of tungsten ammunition core can’t pollute ground water and solve their cleanup headaches. Environment protection becomes more and more urgent and important to human beings.
Besides, lead-free ammunition cores are designed for explosive performance; great accuracy and total disruption make it ideal varmint rounds, with a tungsten-based ammunition core and a poly-tip to provide devastating performance at both short and extended distances. Those properties and military performance are superior to lead cores.
Tungsten Ammunition Core Applications
As the above advantages, tungsten ammunition cores are mainly adopted for the following applications:
Small caliber ammunition Medium caliber ammunition Lager caliber ammunition Amor piercing ammunition Semi-automatic ammunition Revolver ammunition Bullets for rifle/hunting gun Missiles Cannon bullets
Smal l Ca l iber Ammuni t ion
What Is Small Caliber Ammunition?
Caliber is generally the measure of a bullet's diameter; the higher the caliber, the bigger the bullet, and
generally the larger the game it can be used for, it is also called small caliber ammunition. The first consideration when buying ammunition is the caliber. Obviously the caliber has to match that of the rifle that you plan to use. Always make sure that you use only the exact same caliber that is stamped on the barrel or receiver of your rifle; using any other caliber may result in serious or even fatal injury to you. The second consideration should be the material, to protect the environment, and also to have a good performance, tungsten material is more and more popular for both national defense and civilian areas.
Tungsten Small Caliber Ammunition Sizes
The caliber of small caliber ammunition could usually rages from 4.6 mm to 12,7 mm, which includes combat and premium projectiles, cartridge technology and commercial brands, etc. The small caliber ammunition is usually available in the following sizes:
4.6 mm-Ball shape 5.56 mm-Ball shape 7.62 mm-Ball shape .308-as per design .338 cal- as per design 9 mm- as per design 12,7 mm-Ball shape
Because of the good machinability of tungsten material, tungsten small caliber ammunition could be machined as per various with high properties different from other material such as lead.
Tungsten Small Caliber Ammunition Types
The types and construction of the ammunition are also important considerations.
Varmint hunting requires a bullet with a thin jacket and soft core, for rapid expansion and fragmentation inside these tiny targets. At the other end of the spectrum, bullets designed for the largest for game feature a thicker or tapered jacket, often bonded to the bullet's core, in order to provide for deep penetration and controlled expansion while retaining most of the bullet's weight. For deer-sized game, bullets are generally constructed with a softer point, as these animals lack the thicker hides and tougher bones of moose and bears.

For deer-sized game, bullets are generally constructed with a softer point, as these animals lack the thicker hides and tougher bones of moose and bears.
If you shoot a lever action rifle with a tubular magazine, your bullet style will usually be limited to bullets that have a round or flat nose to prevent a chain reaction detonation of the rounds that are lined up tip-to-primer in the magazine. However, most bullets feature a pointed or "spitzer" tip, for increased ballistic efficiency. The main exception to this is large-for-caliber bullets, such as the 220 grain bullet for a .30-06 Springfield mentioned. Such bullets often feature a round nose as well, as they are generally designed for use at short ranges or heavy cover. Therefore, if much denser, then short range would be better.

What Is Medium Caliber Ammunition?
Medium caliber ammunition usually includes 20mm, 25mm, 30mm and 40mm armor piecing, high-explosive, smoke, illumination, training and anti-personnel cartridges with the capability to defeat light armor, material and personnel targets. The 20mm cartridge is a multi-purpose tracer, used in the Counter-rocket system. The 25mm target practice, high-explosive incendiary and armor piercing cartridges are fired from the M242 Cannon. Medium caliber ammunition is dependent on the weapons platforms currently in use. A variety of tests were conducted to determine whether tungsten-core bullets were safer than lead. Therefore, medium caliber ammunition are usually made by tungsten material now.
Tungsten Medium Caliber Ammunition Sizes
The caliber of medium caliber ammunition could usually rages from 12.7 mm to 57 mm, which includes range of combat- and training ammunition for Army, Navy and Air Force applications, etc. The medium caliber ammunition is usually available in the following sizes:
12,7 mm-Ball shape 20mm-as per design 25mm- as per design 27mm- as per design 30mm - as per design 35mm- as per design 40mm- as per design 40mm AGL - as per design 57mm- as per design
Because of the good machinability of tungsten material, tungsten medium caliber ammunition could be machined into different shapes as per various drawing design with high properties which is completely different from other material such as lead.
Tungsten Medium Caliber Ammunition Applications
Multinational missions in war zones and trouble spots are placing new requirements on armies, navies and air forces. Many of the most popular cores today feature to tungsten material but not lead slug. Tungsten help to prevent or damage to the core that can result from repeated loading and unloading in a rifle's magazine and chamber, which can then hurt the bullet's ballistic efficiency and performance. Tungsten medium caliber ammunition offers automatic cannons, weapon systems and ammunition which cover the full range of present and future threat scenarios and can be deployed from land, sea or air. The main product groups encompass vehicle-mounted armaments, aircraft cannon systems and naval guns, including their ammunition as well as ammunition for air defense systems. Due to these applications, tungsten medium caliber ammunition makes weapon systems featuring easy handling, cost efficiency and operational reliability.

Tungsten A l loy Armour-P ierc ing Discard ing Sabot
Armour-Piercing Discarding Sabot
Armour-piercing discarding sabot (APDS) is a type of kinetic energy projectile fired from a gun to attack armoured targets. Tungsten APDS rounds are sabot rounds and were commonly used in large calibre tank guns, but have now been superseded by armour-piercing fin-stabilized discarding sabot (APFSDS) projectiles in such guns. However, APDS rounds are still commonly used in small or medium calibre weapon systems. For a given calibre, this type of ammunition can effectively double the armour penetration of a gun, compared to those firing armour-piercing (AP), AP - capped (APC), or APC + ballistic cap (APCBC) projectiles. The Saboted light armor penetrator concept applies this technology to small arms calibres.
The sub-projectile of the tungsten alloy Armour-piercing discarding sabot (APDS consists of a tungsten alloy high density core with a penetrating cap, enclosed within a high strength sheath (steel) with a lightweight alloy (aluminum-magnesium alloy) ballistic cap. For modern small/medium calibre APDS projectiles, the core is not sheathed and the ballistic and penetrating caps are combined. A tracer element may be added to the APDS sub-projectile, for large calibre weapons this is part of the outer sheath, for small/medium calibre weapons it is contained within a hollow cavity in, or attached to, the base of the core. Most modern APDS projectiles used high strength shock resistant tungsten alloys. The main constituent is tungsten, alloyed or sintered with/to cobalt, copper, iron or nickel.
Sabot DiscardTungsten-alloy-military-spheres
When a large calibre APDS is fired and while still within the bore, the setback forces shear the forward petals, partly unlocking the sub-projectile from the sabot, but still holding it rigidly within the pot. Gas pressure is used to delay the unlocking of the pins holding the rear part of the sub-projectile by gyroscopic forces. Once outside the barrel, the pins, centering band and forward petals are released or discarded by projectile spin, the aerodynamic drag removes the pot/base unit. As an APDS sub-projectile does not require driving bands and the core is supported at the base and ogive region, a far more aerodynamic projectile shape can be chosen. This, in combination with the sub-projectiles’ higher sectional density, gives the resulting sub-projectile vastly reduced aerodynamic drag in comparison to the APCR
To allow increased impact velocity, a stronger penetrator material was required. The chosen new penetrator material was tungsten alloy(WHA), due to its greater strength and its ability to withstand the greater shock and pressure generated during a higher velocity impact. As the density of WHA is twice that of steel, such a shot was too heavy at full bore to be accelerated to a sufficient muzzle velocity.

Tungsten A l loy Green Bu l le t
Numerous countries have used tungsten and various tungsten alloy green bullet for a number of years because of its high density and resulting penetrating power for armor piercing rounds.
Are there tungsten alloys in the Army's "green bullet"? The tungsten alloy green bullet is a common term for the lead-free, small arms ammunition developed by the Army in an effort to provide soldiers with ammunition that is environmentally friendly. Military Tungsten alloy are used in the "green" or lead-free bullet. Tungsten alloy green bullet typically contains tungsten that is mixed together with either nylon or tin. Tungsten
alloys, on the other hand, contain other metals, such as nickel, cobalt, iron, or copper, which are heated to high temperature that allows the materials to bond together. While the tungsten alloy green bullets have been used in training operations at a limited number of Army installations, it has not been used on the battlefield.
More than 90 million rounds of the tungsten alloy green bullet have been used in the United States, since its introduction. It relies on a blend of tungsten and nylon, or tungsten and tin. That gives the bullets the same density and firing properties as the original, but without using lead. Tungsten was considered non-toxic. Tungsten alloys are dense heavy metal composite materials used primarily in military applications.
Tungsten Bu l le t
Tungsten bullet is made of tungsten alloy material and used as the Penetrator Shell core which could Penetrate enemy tanks armored.Tungsten bullet have a equivalent destructive power with uranium bullet and could replace the uranium bullet bomb used in the tank.
Uranium bullet has caused environmental pollution and damage to human after The Gulf War and the Balkans
war.The soldiers would suffering from cancer for use uranium bullet bomb.Uranium is radioactive, it is generalized nuclear weapons which would hurt the troops.Concerning the security issues, US arms manufacturer has decided to stop the production of uranium ammunition.
US Navy have phased out the uranium weapon in 10 years,and gradually use the tungsten bullet which is nontoxic and nonradiative. For the USA have stop the production of the uranium weapon, UK can only be phased out such weapons.The UK defense department have improved that the tungsten bullet have a equivalent destructive power, with the uranium weapon.They have master the evidence of the harmful that caused by the uranium weapon.
High density tungsten alloy is a new material with new structure. It has a High velocity, low ballistic stretching, flight time is short, high accuracy and penetration strength and it could shot fast moving objects. In contrast to the hard steel core, tungsten alloy bullet have a nice ductility and has a fast piercing speed. Tungsten bullet have been widely used at home and abroad.
Tungsten A l loy Submar ine Counterweight
Tungsten alloy submarine counterweight can decrease the size of counterweight with its high density so that it can contribute to the distribution of weight and improve sensitivity of control mechanism. When a heavy article needs to be put into a small space, tungsten alloy is the best ideal materials. Submarine counterweight replaces those products which are toxic and hazardous for its non-toxicity and environmental protection. Compared with steel, tungsten has higher hardness and density. Tungsten
alloy lead products of the same kind by 30%. Otherwise, compared with lead, the weight of Tungsten alloy submarine counterweight which has the same volume is heavier than lead by twice. Tungsten alloy is hard and it has stable chemical property. Its shape and structure can be maintained for a long time.
Submarine counterweight needs to reach to a definite magnitude so that submarine can realize immersion. Submarine cannot submerge when the weight which combines with submarine and the water in its sump is lighter than the displacement of submarine. So counterweight needs to be installed at the bottom of submarine. Tungsten alloy submarine counterweight is used to increase the weight of submarine.
Tungsten alloy submarine counterweight can be made on the basis of displacement of submarine. The counterweight usually cannot be dismantled when it has been installed. Sometime, submarine may dive at different depth. Tungsten alloy submarine counterweight can be added by its self in terms of depth. What's more, Tungsten alloy submarine counterweight can be made in line with the request for submarine.
Tungsten A l loy Warhead
Tungsten alloy is kind of alloys which has thermostability. The high initial velocity of bomb relies on high temperature and high pressure inside bomb. So tungsten alloy warhead need to endure high temperature and pressure inside bomb. For its thermostability, tungsten alloy was once used as tungsten wire. Tungsten alloy is also a kind of metal materials which has high density, resistance to compression and corrosion. Tungsten alloy do not react with strong acid and alkali under the normal temperature and pressure. The density of tungsten alloy can reach greatly. The equalizer of armor piercing discarding sabot is made by tungsten alloy. Tungsten alloy is a kind of environmental protection metal materials. People are always appealing to environmental protection. In the past, the bullets were made by lead, so it caused pollution to local environmental after using. To avoid the pollution to environment, environmental protection material should be used as far as possible. So tungsten alloy is well known for its advantage of environmental protection. Tungsten alloy can be used as tungsten alloy warhead.
Tungsten alloy warhead is a kind of warheads which are adopted by air-to-air or air-to-ground guided weapons. Actually, those warheads are finished components of aerial bomb. They can be directly put into the missile without modifying structure.
Tungsten alloy warhead is produced, stored and transported by the bundle of diameter. Tungsten alloy warhead can be directly put into bomb without processing. So it lowers the cost of producing, utilizing and maintaining and reduces the set-up time for fighting. Tungsten alloy warhead contains dynamite warhead whose weight includes 500pound, 1000pound and 2000pound and penetrating warhead.
Tungsten A l loy Ant i -mater ia l R i f le Bu l le t
Tungsten alloy is a kind of composite materials that tungsten whose quality fraction is 80%~98% distributes to Ni-Fe-W sosoloid. As it is wished, tungsten alloy combines with the high density, high strength of tungsten and good ductility of matrix. So it has a series of properties of physics, chemistry and mechanics. Tungsten alloy has wide usage in military industry with its good properties. One of applications is tungsten alloy anti-material rifle bullet.
Anti-material rifle continues the thinking of anti-tank rifle which was used in twice World War. It can launch large caliber machine gun bullet. Cooperating with anti-material rifle bullet, it can penetrate light tank which has thin armor, and kill personnel in the tank. It can also kill sniper hiding behind blindage. It is mainly used for dealing with vehicles, oil depot, radar, telescopic surveillance mirror, copper flying at low altitude and jet landing on the ground. Just as anti-tank rifle, anti-material rifle focuses on penetration and it is dominated by high power bullets such as tungsten alloy anti-material rifle bullet. It can be used by infantry, highly improving combat capability of infantry platoon. For example, utilizing anti-material rifle bullet, M82A1 anti-material rifle makes up fire continuity and power of M24 sniper rifle in Afghanistan War. It is said that a Taliban official was killed by M82A1 from the distance of 1760 yards (1600m) on his way to vehicle. Otherwise, the U.S. Coast Guard also uses M82A1 in drug enforcement, efficiently striking high-speed skiffs which carrying drug near the coat.

The most outstanding property of tungsten heavy alloy is high proportion, also called as high density. The density of tungsten heavy alloy can reach 18g/cm3, which is higher than steel (7.8g/cm3) by 2.3 times. So the fracture surface of bullet has high density which highly improving speed of bullet and penetration to steel plate during flying.
Tungsten alloy machine gun bullet is kind of machine gun bullet which has good properties, developed form 1970's. The warhead of machine gun bullet has the properties of high initial velocity, low trajectory, short flying time, high accuracy, high penetration, etc. by adopting decorticating theory, new structure and material of tungsten heavy alloy. It can deal with high-speed target efficiently. The fracture surface of bullet has high density. The tungsten alloy core has good ductility, which is contrary to the broken of hard steel or tungsten carbide core during penetration. Tungsten alloy machine gun bullet has excellent property of second penetration and penetrates to armor in splash type. Tungsten alloy machine gun bullet has significant penetration to composite armor which has big impact angle, or layered construction. Tungsten alloy core has been widely adopted for large caliber bullet or small caliber shell, as ammunition to target which has light armor such as panzer or attack helicopter.
Chinese Type 84 12.7mm tungsten alloy machine gun bullet is equipped with Type 77 12.7mm anti-aircraft machine gun and is in common use in Type 54 12.7mm anti-aircraft machine gun. The quality of warhead is 28g and quality of core is 22g which is 78.6% of warhead. The diameter of core is 7.9mm. Subcaliber ratio (core diameter to warhead diameter) is 0.62. Initial velocity of bullet is 1150m/s. It can penetrate 15mm homogenous steel alloy plate in 45°impact angle from distance of 20m. The maximum distance of penetration to 20mm homogenous steel alloy plate is 150m in 45°impact angle. However, Chinese Type 54 12.7mm armor-piercing incendiary (API) ricochets from distance of 9.5m. it can
only penetrate 15mm steel plate in 30°impact angle from distance of 830m and penetrate 20mm steel plate from distance of 125m. So, 12.7mm tungsten alloy machine gun bullet has better penetration to steel plate in big impact angle.
