Corrosion Resistance

What is Corrosion Resistance?

The ability of a metal to stay unattacked in air, water or food acids. Aluminium has it not because it is unreactive but because a thin, tough, continuous layer of aluminium oxide forms on its surface and keeps air and water away from the metal underneath.

This definition is part of the Metals chapter in Cambridge O Level Chemistry.
