White fused alumina,is made from high quality alumina by being melted above 2000°C in the electric arc furnace. It is characterized by high purity, great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance. Its hardness is a little higher than brown fused alumina. It is with low toughness, great grinding ability, small heat and high efficiency. White fused alumina can be made into all kinds of abrasives, suitable for grinding high carbon steel, high speed steel, stainless steel and other fine-grained abrasives; it can be also used for precision casting and high-refractory materials.  

White Fused Alumina has white colour and a little higher hardness and toughness comparing with the brown one. 

High Alumina Content
White Fused Alumina has Aluminium Oxide(Al2O3) content of more than 99%, which guarantee the great performance in fireproof and refractory application
High Purity
White Fused Alumina has very limited impurities, usuallyNa2O≤0.4%,SiO2≤0.15% andFe2O3≤0.15%.
High Hardness
The high content of Al2O3 (Aluminum Oxide) obtainsWhite Fused AluminaMosh Hardness of 9 and wide application for cutting and grinding wheels, also, White Fused Alumina can be used for coated abrasives, sandblasting media for surface preparing and polishing of metallic and ceramic products.
Sharp Edges
White Fused Alumina is a crystal mineral with sharp edges and widely used in sandblasting,cutting and grinding abrasives.
