Aluminum oxide powder for grinding
White corundum is made of high-quality aluminum oxide powder, crystallized by electrofusion refining, with high purity, good self-sharpness, acid and alkali corrosion resistance, high temperature resistance and stable thermal properties. Its hardness is slightly higher than brown corundum, with a slightly lower toughness, high purity, good self-sharpness, strong grinding ability, low heat generation, high efficiency, acid and alkali corrosion resistance, and high-temperature resistance and good thermal stability. It is suitable for grinding high carbon steel, high speed steel, stainless steel and other fine abrasives, and can also be used in precision casting and high grade refractory materials.
It is suitable for grinding high carbon steel, high speed steel, hardened steel and other materials with high hardness and high tensile strength. It can also be used as grinding and polishing material. Precision casting, spraying materials, chemical catalyst carriers, special ceramics, grinding wheels, steelmaking, advanced refractory materials, etc. It is characterized by strong cutting power, good chemical stability and good insulation.
