Black Aluminum Oxide is produced by fusing bauxite, iron oxide and other elements in an arc-furnace. The resulting product has a moderate hardness, high toughness, high temperature resistance, good thermal stability, and excellent self-sharpening.

Black Aluminum Oxide, due to its thermal stability and low heat generation when polishing, is used to polish metal pieces, especially stainless steel, producing a high smooth finish with little surface discoloration. It is also used in resin bonded abrasives, blasting applications, as anti-skid surfacing material, abrasive belts, flap wheels, fiber wheels, and other polishing and lapping applications.
