White Fused Alumina (WFA)
Fused White Alumina is produced by fusing calcined alumina in an electric arc furnace under carefully controlled conditions. The material produced is white in color, dense and has predominantly large crystals of Alpha Alumina. WFA is raw material characterized with high hardness, high purity, chemical stability, a high melting point, and large crystal size.
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.
