The black corundum abrasives produced by our company have the advantages of moderate hardness, high toughness, high temperature resistance, stable thermal performance, high cleanliness, uniform particle size, strong grinding force, good wear resistance, high working efficiency and so on.
Product Induction:
Our Black Fused Alumina Powder is a dark gray crystal body made α-Al2O3 and ferropicotite as main ore in the electric arc furnace by smelting the bauxite .Its character is that the content of Al2O3 is low, and there is a certain amount of Fe2O3, there is a small amount of SiO2 and TiO2. It also has the characteristics of moderate hardness, high toughness, high temperature resistance and stable thermal performance. It is mostly used for free grinding.
