White Fused Alumina/ White Aluminum Oxide/ White Activated Alumina

 

White fused alumina/White aluminum oxide (WA) is electrically fused in the furnace with high grade Bayer processed alumina as raw material. It has high purity, ability of self-sharpening, better cutting, less heat emit, higher Efficiency, acid and alkali resistance, good thermal stability. Abrasives tools made of it are suitable for grinding high-speed, high carbon steel, etc. It also can be used as materials for grinding and polishing, precision casting, spaying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials etc.
