Aluminium oxide is the main component of the principal ore of aluminium (bauxite), and the main component of the gems ruby and sapphire.

Aluminium oxide is responsible for metallic aluminium's resistance to weathering. Metallic aluminium is very reactive with atmospheric oxygen, and a thin layer of aluminium oxide quickly forms on any exposed aluminium surface. This layer protects the metal from further oxidation.

Powdered aluminium oxide is frequently used as a medium for chromatography.
