White Aluminum Oxide

White Aluminum Oxide

white aluminum oxide is made of aluminum oxide powder and smelted in high temperature in an electric arc furnace. Al2O3 content is generally higher than 98%, hardness is higher than brown aluminum oxide, toughness is lower than brown aluminum oxide, and has good cutting performance. An abrasive tool made of the same is suitable for grinding hardened alloy steel, high speed steel, and the like. Fine-grained milling can also be used as precision casting.
