Aluminium Oxide is the second hardest abrasive after diamond. The hard and crystalline nature of Aluminium Oxide makes it a very fast cutting abrasive which is also used for extensively in the manufacture of coated and bonded abrasives. It can be used for the roughest cutting down to a precision micro finish on high spec parts. Aluminium Oxide is also suitable for use where no ferrous contamination can be tolerated.
There are several methods of producing Aluminium Oxide from bauxite. Each method produces a different level of quality suitable for differing end uses.
The Aluminium Oxide sold by Industrial Minerals and used in the abrasive industry is normally produced at very high temperatures in controlled arc furnace. The degree of control allows a very hard product to be produced and at a typical hardness of 9.0 Mohs, a product ideal for abrasive users.
