    Black aluminium oxide is also known as low aluminum corundum. (AI2O3) 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 伪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.

    grit size: 12-220;
    Micropowder: 240-1200.
