Aluminum Oxide
AL2O3 have the characteristics of high hardness (second hardest mineral after diamond), sharpness, tenacity, stable chemical property, heat resisting and corrosion resisting, This sharp angular abrasive is fast cutting and is silica free. It gives a matte finish, or produces anchor patterns on most metal surfaces and can be used economically in a closed system blasting system.
White Aluminum Oxide
Electrically fused from Bayer alumina, white colour, its hardness is a little higher, but toughness slightly lower than that of Brown Aluminium Oxide used for fabrication of bonded and coated abrasive products for the grinding of the steels with great hardness, such as high carbon steel, alloy steel, and high speed steel. Its non-abrasive uses are precision casting molding sand, spray coating material, catalyst carrier, high temperature ceramic, and super refractory material, etc.
