ALUMINIUM

3rd most plentiful element in the earth's crust

content

In nature, aluminum is found only in chemical compounds with other elements such as sulphur, silicon, and oxygen.

Pure, metallic aluminum can be economically produced only from aluminum oxide ore.

occurs in all types of clay

ALUMINIUM8% of the planet's soil and rocks47% oxygen 28% silicon

most useful ore for producing pure aluminum is

RAW MATERIALSBAUXITE main constituents are aluminium oxides, iron and silicon consists of 45-60% aluminum oxide along with various impurities such as sand, iron, and other metals.

some deposits are hard rock, most consist of relatively soft dirt that is easily dug from open-pit mines

Major producers include Australia, Brazil, Jamaica and Surinam. Australia produces more than one-third of the world's supply

It takes about (4 lb) 2 kg of bauxite to produce (1 lb ) 0.5 kg of aluminum metal.

Caustic soda (sodium hydroxide) is used to dissolve the aluminum compounds found in the bauxite, separating them from the impurities

The largest and most lucrative bauxite deposits are located around the Equator.

MANUFACTURING

The production of 1Kg of aluminium requires around 2Kg of alumina. The production of 2Kg of alumina requires about 4Kg of bauxite.

AppearanceSmooth bright finish

Strength tensile strengths Al alloys 70- 700 MPa. The range for alloys used in extrusion is 150 300 MPa. does not become brittle at low temperatures.

Instead, its strength increases. At high temperatures, aluminiums strength decreases. At temperatures continuously above 100C, strength is affected to the extent that the weakening must be taken into account

WeightAluminium is light with a density one third that of steel, 2.700 kg/m3.

..Conductivityexcellent conductor of heat and electricity.having 59% the conductivity of copper, both thermal and electrical, while having only 30% of copper'sdensity.

JoiningFeatures facilitating easy jointing are often incorporated into profile design. Fusion welding, Friction Stir Welding, bonding and taping are also used for joining

Screening EMCTight aluminium boxes can effectively exclude or screen off electromagnetic radiation. The better the conductivity of a material, the better the shielding qualities.Linear expansionCompared with other metals, aluminium has a relatively large coefficient of linear expansion

MachiningAluminium is easily worked using most machining methods milling, drilling, cutting, punching, bending, etc.the energy input during machining is low.

FormabilityAluminiums superior malleability is essential for extrusion. With the metal either hot or cold, this property is also exploited in the rolling of strips and foils, as well as in bending and other forming operations.aluminium is the most common element in the Earths crust. Aluminium compounds also occur naturally in our food

ReflectivityAluminium is a good reflector of both visible light and radiated heatNon-magnetic materialAluminium is a non-magnetic (actually paramagnetic) material. To avoid interference of magnetic fields aluminium is often used in magnet X-ray devices.

Corrosion resistanceAluminium reacts with the oxygen in the air to form an extremely thin layer of oxide. Though it is only some hundredths of a (my)m thick

(1 (my)m is one thousandth of a millimetre), layer is dense and provides excellent corrosion protection. layer is self-repairing if damaged.Anodising increases the thickness of the oxide layer and thus improves the strength of the natural corrosion protection. Where aluminium is used outdoors, thicknesses of between 15 and 25 m (depending on wear and risk of corrosion) are common.Aluminium is extremely durable in neutral and slightly acid environments.In environments characterised by high acidity or high basicity, corrosion is rapid.

FLASHING TOSTONECORNICE

Flashing styles

A square or rectangular gutter that is used within the boundaries of the roof. It may be formed between a roof surface and a parapet wall or between two roof surfaces. Available with infold, outfold, splashback and squashfold edges. This gutter is usually supported on a box gutter board to improve strength And stiffness and to Minimise damage caused byroof traffic.BOX GUTTER

INDUSTRIAL EAVE GUTTERSA purpose made external gutter which is located at the edge of an industrial roof. It is usually supported by heavy gauge brackets that have been designed specifically to suit the industrial eaves gutter shape. When made in larger sizes special attention should be given to minimising oil canning of flat surfaces by introducing additional ribs into the design.

A shallow gutter formed to suit the angle between two internal slopes of a roof. Its design will usually include a return at each edge to minimise the possibility of water spillage into the roof space. Depending on the size and application additional internal stiffening ribs may be included.VALLEY GUTTERS

A half round segmented gutter formed into a trough. It is formed between a roof surface and a parapet wall or between two roof surfaces and is available with infold, outfold, splashback and squashfold edges. Usually supported by heavy gauge straps, trough gutters are very efficient and have better self cleaning properties than box gutters. In most cases the depth will not exceed half the widthTROUGH GUTTER

used where two walls meet to form an external corner.

Where used with sheet walling it should lap at least one rib and a recommended two ribs for maximum water proofing

used to prevent water from penetrating the space where a vertical surface intersects a roof. it should lap at least one rib and a recommended two ribs for maximum water proofing. Wider apron flashings are advised when the base of the flashing faces into the prevailing wind.

used to finish the base of a vertical surfacealso provides an edge to an adjoining soffit.Typical applications are in facades and to finish overhanging canopies. The flashing also prevents water contact to the ends of sheeting.FOOT MOULDS

used to seal the join between the end of a roof and masonry wall. A V groove end locates into either a preformed reglet, or a cut in the masonry wall providing a water resistant join to the roof and wall connection. When installed, pole plate flashings (often called chimney flashings) can either be stepped to conform to brick courses or left straight, for a more modern appearance.

used to cap building framework and external brickwork at the base of a window or door frame.

covering over the ridge between two slopes. The size of the edge break should conform with the rib height of the steel roofing to which the ridge is attached. Good roofing practice is to notch this edge break to neatly fit around each rib of the roof sheet.

used around chimneys. made as a two piece flashing to provide flexibility in installation.

used to cap the ends of vertical sheets or masonry walls. A stiffening edge or break is often applied to the legs of the parapet cap for a more appealing appearance.

used AT junction between a fascia or barge board and roof sheeting. The size of the edge break should conform with the rib height of the roofing to which the ridge is attached.

TYPES OF FLASHINGS

When aluminum is passed between rolls under pressure, it becomes thinner and longer in the direction in which it is moving.

This process is basis for forms: plate

sheet foil.

Aluminum can be rolled and re-rolled until it reaches the desired thickness or gage.

When the rolling process is stopped largely determines whether the final product will be plate sheet or foil.

Note: There is an overlap (0.006-0.0079 inch) in the thickness ranges defined for foil and sheet. Foil products in this gage range are supplied to foil product specifications, and sheet products are supplied to sheet specifications.Sheet and Plate sheet (0.249 to 0.006 inch)plate (0.250 inch thick or more)foil (0.0079 inch or less).Thickness

Aluminum Powder and PasteAluminum powder and paste are used in a wide variety of applications, ranging from paints and coatings, chemical andmetallurgical applications, topropellants and explosives.

The use of recycled aluminum saves 95 percent of the energy, and avoids 95 percent of the emissions, associated with the production of the metal from ore, and it reduces the amount of waste consigned to landfills

With appropriate sorting, scrap aluminium can advantageously be recycled to produce the same sorts of products over and over again.

Requires only 5% of the original energy input.

So easy to recycle:perfect eco-metal. Very little aluminium is lost in the remelting process..RECYCLING
