Black aluminum oxide supplied by our principles, which has good features as high hardness, strong tenacity, better bonding ability and hydrophilicity, giving less heat, good self sharpening, smooth surface and high finish. It's suitable for polishing various spare parts such as, bicycles, sewing machine, hard metal tools, medical apparatus, time pieces, glass products and stone grinding. It's also the right material for making abrasive tools: fiber-reinforced cutting wheels, grinding wheels, sand cloth paper and paste.

White fused aluminaWhite aluminum oxide (WA) is electrically fused in the furnace with high grade Bayer processed alumina as raw material. It has high purity, ability of self-sharpening, better cutting, less heat emit, higher Efficiency, acid and alkali resistance, good thermal stability. Abrasives tools made of it are suitable for grinding high-speed, high carbon steel, etc. It also can be used as materials for grinding and polishing, precision casting, spaying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials etc. The physical and chemical analysis Al2O3 MIN 99.53%Na2O MAX 0.4%Fe2O3 MAX 0.1%SiO2 MAX 0.1%Crystal system HexagonalColor WhiteMicro Hardness HV2200-2300Grinding ability (compared with diamond as one) 0.12Hardness (mohs) 9Ture density 3.9 gcm3Bulk density 1.75-1.95 gcm3 Purpose Specifications Chemical Composition Magnetic material Content (%) MaxAbrasives Grade AL2O3 Min.
