White fused aluminashort for WFA, also known aswhite fused aluminum oxide,white aluminum oxide, white corundum, is a kind of high-grade refractory and abrasives, was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3. The micro hardness of the product is 2200-2300kg/mm2. The abrasive tools made of it are suitable for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as sandblasting, lapping and polishing medium, precision founding sand, coating materials, catalyst carrier, special ceramics and super refractory materials.
