Summary

Aluminium atoms are very reactive because of their atomic structure. This is the reason why aluminium never occurs in the pure form in nature, but always as a compound with other elements, especially oxygen. Even industrially produced pure aluminium reacts immediately with air to form an oxide layer, which protects the metal against corrosion.

Aluminium can be alloyed with small quantities of other elements. The most important alloying elements are magnesium, silicon, manganese, iron, copper and zinc. It is possible to improve important mechanical properties of the metal in this way.
