White Fused Alumina is used in many applications including grinding and cut off wheels, refractories and ceramic shapes, coated abrasives, investment casting shells, laminates, coatings, blasting abrasives, lapping and polishing, etc.
White Fused Alumina (WFA) is obtained from the fusion of high purity calcined alumina in electric arc furnaces. WFA is raw material characterized with high hardness, yet friable with high purity, chemical stability, a high melting point, and large crystal size.
White Fused Alumina for refractory
White fused aluminum oxide obtained from the fusiion of calcined alumina in electric arc furnaces. Comparing with brown fused alumina. It is also characterized by its high purity, acid and alkali resistance, good thermal stability. It's the high grade refractory materials.
