White Fused Aluminum Oxide (WFA)

White Fused Aluminum Oxide (WFA) is produced from the fusion of high purity calcined alumina in electric arc furnaces. It characterized with high hardness, yet friable, high purity, chemical stability, a high melting point, and large crystal size. White Fused Aluminum Oxide 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 etc. See below for product information relating to your application.
