White Corundum

  Is based on high-quality aluminum oxide powder as raw material, formed by the crystallization of fused refining, high purity, self-sharpening, good acid and alkali corrosion, high temperature thermal stability performance, it is slightly higher than the brown corundum hardness, toughness is slightly lower, high purity , self-sharpening good grinding ability, heat a small, high efficiency, acid and alkali corrosion, high temperature thermal stability. Made with its abrasive for grinding high-carbon copper, high-speed steel.
