Aluminum is used extensively in almost countless application because of its high strength combined with low density. Also it is corrosion resistant to the atmosphere as a thin film of aluminium oxide forms over aluminium surfaces which protects it from further corrosion. Also, aluminium is non-toxic making it suitable for application involving contact with food products.
The most extensive and biggest use of aluminium is in packing. It used for packing in various forms such as cans, foils, tubes, and bottle tops.
Second biggest use of aluminium is in transportation it is widely used in most transport vehicles. It is particularly suited for aeroplanes. A modern aeroplane contains about 80% aluminium by weight, A Boeing 747 contains about 75 tons of aluminium.
Electrical transmission is another very big application area for aluminium. It has about 63% of electrical conductivity of copper but only half the density. That makes it a very attractive substitute for copper in electric cables and transmission lines. Particular for bare conductors of transmission lines, aluminum is is the only choice.
Aluminum find very big application in construction industry in form of window and door frames, cladding, and roofing. Aluminium is also used for painting other surfaces.
Aluminium is also used extensively for making stylish and light weight furniture. It is particularly popular for folding and other type of furniture which is intended to be shifted and stored away frequently.
IN addition to these major areas identified there are so many other applications that together account for a large quantity for aluminum, For example it is used for making utensils, golf clubs and tennis rackets.
