Aluminum oxide white fused alumina for polishing

Aluminum oxide white fused alumina for polishing

White fused aluminain arc furnace with high grade processed alumina as raw materials. It has higher hardness and slight lower toughness comparing with brown fused alumina. 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. As the abrasive materials, it is suitable for grinding high-speed, high carbon steel, as loose grains, it widely used for bonded and coated abrasives, polishing, precision casting and so on.Usage:1. For abrasive materials, sandblasting2.For refractory raw materials, Precision casting.
