More about Aluminum…• Aluminium is the most widely used

non-ferrous metal• Over-all, it is the second most widely

used metal after iron.• Aluminium is almost always alloyed,

which markedly improves its mechanical properties, especially when tempered.

Reliability of Aluminum• When it is cold-worked, the metal

strengthens by double.• It does not oxidize quickly in air due • noted for its low density and for its

ability to resist corrosion• It can be recycled repeatedly, quickly

and cost-effectively
