1. WA white fused aluminum oxide powder
White fused aluminium oxide is electrically fused in the furnace with high-grade alumina powder as raw materials. It has higher hardness and slightly lower toughness than brown fused aluminium oxide , characte-rized by its high purity,strong grinding ability,Abrasives tools made of it are suitable for grinding high speed steel,etc. It also can 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.

3. Advantages:
(1) Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.
(2) Good hardness, longer life.
(3) Chemical washed and water washed good cleanness.
(4) Special treated products get higher purity, better toughness, and better grinding effect.
