material, and it is a dark gray crystal body made α-Al2O3 and
ferropicotite as main ore in the electric arc furnace by smelting
the bauxite. It has characteristics of moderate hardness, high
toughness, high temperature resistance, and stable thermal
stability. 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. Â
