WHITE ALUMINUM OXIDE (WA)  
     
 
 
     
  White Aluminum Oxide is electrically fused in arc furnace with high-grade bayer processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown aluminum oxide.
It is also characterized by its 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 fine grinding of high carbon steel, high-speed steel and stainless steel. It also can be used as materials for grinding and polishing, precision casting, spraying and coating, medium body for chemical industry special ceramics and high-grade refractory materials.
