ALUMINIUM

A metallic element (Al), it is the third most abundant element on the earth's crust (after oxygen and silicon). Its characteristics of ductility, softness, lightness and resistance to oxidation make it suitable for industrial processes including casting, extrusion, forging, stamping and rolling. It is mainly extracted from bauxite (primary aluminum) or obtained from recycled sources (secondary aluminum).
