Aluminium oxide - Wikipedia

Aluminium oxide is used for its hardness and strength. Its naturally occurring form, Corundum, is a 9 on the Mohs scale of mineral hardness (just below diamond). It is widely used as an abrasive, including as a much less expensive substitute for industrial diamond. Many types of sandpaper use aluminium oxide crystals.
