Brown aluminum oxide refractory abrasive 1-3mm alumina price
1 Description
Brown corundum is made of bauxite, anthracite and scrap iron as the main raw materials by smelting at high temperature in the arc furnace. It is brown in color, with good toughness, micro–hardness of 1800-2200kg /mm2, volume density ≥3.85g/cm3, and high temperature resistance and fire resistance up to 1850℃.
