Oft associated with beautiful tableware, coins, and silverware, silver

alloys and pure silver are striving hard to meet an ever-increasingworld demand. From the world of electronics to celebrity circles, this

metal and its alloys are surely in high demand.



Here, we take a quick look at how wholesale silver jewelry New

York is making heads turn, mainly because of silver’s uniqueattributes.

Silver – the Special Metal



Just like gold, also a precious metal, silver is extremely ductile

and malleable. Harder than gold, this lustrous metal is softer than

copper, and can be hammered into sheets that are so thin that an

inch high stack would require at least 100,000 of them for

fulfilling the purpose. Silver boasts of a specific gravity of 10.5, is

harder than gold, and has with a melting point of 960°C / 1760°F -

about 200°F below the melting point of gold.



With purity levels that generally goes up to 99.95% (that is nominally

considered 100%), commercially available silver is rarely pure silver.

The main reason behind it being used as an alloy, and not in its

purest form, is that being ductile, goods made of pure silver are

prone to damages. Today, there are several silver alloy compositions

that are being put to use for silver jewellery, or as electrical

conductors and brazing compositions.



Addition of Copper to Silver

Appropriately hardened by alloying; in most cases, copper is used as

the favorite metal for improving upon the ductility of silver. Copper is

used for the production of sterling silver, a useful alloy that contains

a minimum of 92.5% silver too. Silver-copper modifications andeutectic also contain other elements like tin, cadmium, phosphorus,

zinc, and/ or lithium. Widely applied for brazing purposes, especially

where strong joints with relatively good resistance for corrosion are a

must, sterling silver is used in places where higher strength measures

(at elevated temperatures) are required.



The “Sterling” Mark

Sterling silver represents the most respected and best knownquality marking that’s in use today. The mark “Sterling” assures

buyers that the silver purchased by them has 92.5% of pure metal

by weight; and there is absolutely no stipulation regarding the

remaining 7.5%.



Oxidation of Silver

Silver is known for its affinity for oxygen that increases with

temperature. So, whenever molten silver is exposed to air, it ends

up absorbing about a whopping twenty-two times its total volume

in oxygen. Also, just like silver, copper forms copper-oxide whenexposed to oxygen and depicts a high affinity towards the same

too. This is the reason why air has to be excluded during the entire

casting process; unless internal voids or porosity serve to be a

characteristic of the cast metal. Overall, oxidation has to avoidedwhen silver-copper alloys or sterling silver are melted for casting

into different products.



Application of Silver Alloys

Silver alloys are also intended for industrial applications, wherein

they are generally characterized by their high electrical

conductivity and high mechanical / functional properties. Thesilver alloys that are specifically designed for manufacturing

electrical contacts boast of high corrosion /erosion resistance, and

high temperature resistance. Here, alloy additives are being used

for meeting these requirements; especially in the case of productsthat require dispersion hardening or precipitation hardening. Such

mechanisms are popular in copper alloys and platinum alloys.



Why Silver?

Among the many precious metallic materials that are put into use

in dental applications, such as palladium, gold, and silver; buyers

find significant differences in context with the strength, elasticity

modulus, coefficient of thermal expansion, price, density, melting

temperature, and hardness of these materials. When it comes to

costs, silver alloys are usually regarded as cheaper choices in

relation to other precious materials.
