White fused alumina With high-quality aluminum oxide powder as raw material, the fused extraction from crystal, high purity, good self-sharpening, acid and alkali resistance, high temperature resistance, thermal stability of its hardness is slightly higher than that of brown corundum, toughness slightly low, high purity, good self-sharpening, grinding ability, heat a small, high efficiency, acid and alkali resistance, high temperature thermal stability. Abrasives tools made of it are suitable for grinding, high carbon copper, high speed steel.
