White corundum abrasive is made from alumina as raw material and melted at high temperature. White in color, slightly harder than brown corundum, slightly lower in toughness, high purity, good self sharpening, acid and alkali corrosion resistance, high temperature resistance, strong grinding ability, low heat generation, stable thermal performance. Grinding tools made of white corundum are suitable for grinding high carbon steel, high-speed steel, and quenched steel. White corundum abrasive and sub white corundum abrasive can be used as grinding and polishing materials, as well as precision casting sand, spraying materials, chemical catalyst carriers, special ceramics, and used to make grinding tools suitable for grinding high carbon copper, high-speed steel, etc. White corundum micro powder has a wide range of applications, such as atomization beauty processing of polystyrene or acrylic crafts, sandblasting in TV screen manufacturing, additives for refractory materials and other ceramics.
Abrasive and grinding tools: mainly suitable for sandblasting, grinding, polishing, cutting blades, grinding wheels, bonded grinding tools, coated grinding tools, etc
Refractory materials: precision casting, refractory bricks, castables, etc
