Specification
Aluminium is a silvery-white, ductile metallic element, the most abundant in the earth’s crust but found only in combination, chiefly in bauxite. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. The chief ore of aluminium is bauxite. It makes up about 8% of the Earth’s crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust.
