1. White Fused Alumina Descriptions
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 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, and many, many more. See below for product information relating to your application.
