Description of Black Fused Aluminum Abrasives

Most 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 fused alumina manufacturers 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 also known as low aluminum corundum. (Al2O3) content is 70% ~ 80%, containing more silicon oxide and titanium oxide impurities, It is also a new type product of polishing material, and it is a dark gray crystal body made αAl2O3 and ferropicotite as main ore in the electric arc furnace by smelting the bauxite.

Black Fused Alumina has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability. and it is mainly suitable for free grinding, such as coarse grinding before electroplating products, mainly for polishing and sandblasting of stainless steel, fabricated metal products.
