White Fused Aluminium Oxide for Abrasives
White Fused Aluminium Oxide(White Fused Alumina) is a synthetic corundum made of reduced fusion of high purity alumina powder and other fillings in electric arc furnace under 2000 degree above, also called White Fused Alumina, abbreviated as "WA". Its main chemical content is Aluminium Oxide(Al2O3, 99%min), and little Sodium Oxide(Na2O), Ferro Oxide(Fe2O3) and Silicon Oxide(SiO2). Beause of its high content of Aluminium Oxide, it's very hard, tough and sharp edged, and has very high refractory temperature, and can be used in abrasive tools production, refractory materials, sand blasting, water-jet cutting, steel making, metallurgical, casting, foundry, ceramic industries. We select quality high purity alumina powder and fuse in electric arc furnace by skilled technicians, and excute standard crush, shape improve, sieving, magnetic content removal and grade into standard FEPA grits for abrasives and sand blasting. Our White Fused Aluminium Oxide is pure, hard, sharp-edged, blocky, good self-sharpening. We check our sieves every two months against standard sieves to make sure that our products meet FEPA, JIS or ANSI standard.
