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)
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.
