Introduction of white corundum
The white corundum abrasive is made of alumina by high temperature melting. White, slightly higher hardness than brown corundum, slightly lower toughness. Abrasive 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, precision casting molding sand, spraying materials, chemical catalyst carriers, special ceramics, advanced refractory materials, etc. White corundum abrasive performance : white, harder and brittle than brown corundum, strong cutting force, good chemical stability, and good insulation. The application scope of white corundum abrasive : it can be used for solid structure and coated abrasive tools, wet or dry jet sand, suitable for ultra-precision grinding and polishing in crystal and electronic industries, and making advanced refractory materials. It is suitable for processing hardened steel, alloy steel, high speed steel, high carbon steel and other materials with hard hardness and high tensile strength. White corundum abrasives can also be used as touch media, insulators and precision casting sand.
