Abrasive white fused alumina size F12-F1200

White fused alumina(White aluminium oxide) is electrically fused in the furnace with high grade bayer processed alumina as its raw material. Occupying higher hardness and slightly lower toughness compared with Brown Fused Alumina, it is characterised by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency,acid and alkali resistance, and good thermal stability. Abrasive 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, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials,etc.
