Aluminium is the most abundant metal to be found in the earth's crust. It is extracted from bauxite, hydrated Aluminium oxide, and once in the elemental form aluminium has a silvery appearance.
In its pure form aluminium is light, malleable and ductile. Aluminium is also nonmagnetic and non-sparking. A thin non-conducting oxide layer readily forms over aluminium’s surface in air, and is the reason for aluminium’s excellent corrosion resistance. The addition of small amounts of copper, magnesium, silicon, manganese and other elements along with specific heat treatments can significantly improve the strength of the aluminium. It must be noted that while the addition of these elements increase the strength, they can also decrease the corrosion resistance of the aluminium. The combination of aluminium’s alloys high strength, light weight and good corrosion resistance has resulted in the wide spread use of aluminium alloys in the aerospace industry, as well as other forms of transportation and manufacturing.
The number of applications that aluminium and its alloys can be used for is vast. This ranges from applications such as kitchen foil and transmission lines in aluminium’s pure form, through to transportation (automobiles, aircraft etc.) in aluminium’s alloyed state.
