China Fepa F180 White Fused Alumina for Precision Treatment, Find details about China Abrasive, White Aluminum Oxide from Fepa F180 White Fused Alumina for Precision Treatment
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), Ferric Oxide(Fe2O3) and Silicon Oxide(SiO2). Because 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 execute 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, 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.
