We are a professional manufacture of white fused alumina since 1999. White fused alumina is a high-quality raw material, made of fused refining crystal, high purity, self-sharpening, good acid and alkali resistance, high temperature, thermal properties and stability. it is slightly higher than the corundum hardness, toughness slightly lower, high purity, good self-sharpening, grinding ability, heat, high efficiency, acid corrosion, high temperature thermal stability. Made with the abrasive, for grinding high-carbon copper, high-speed steel.
