Black Fused AluminaMost of Black fused alumina is made in China, which is also known as low aluminum corundum. It is a dark gray crystal, melted in electric arc furnaces by using the bauxite as its raw material. Black fused alumina is characterized by low Al2O3 and a certain amount of Fe2O3 (10% more or less) content, so it has characteristics of moderate hardness, high toughness, high temperature resistance, and high thermal stability.

Black fused alumina is suitable for lapping, polishing and sandblasting of stainless steel and fabricated metal products, optical glass and bamboo products. Furthermore, it's used to make anti-slip material and also the right material for making abrasive tools, such as resin reinforced cutting wheels, grinding wheels, sanding cloth, paper and abrasive compound.
