BFA 60# sandblasting abrasive brown fused alumina price
1 Description
Brown Fused Alumina (BFA) is produced by a reduction fusion of high quality bauxite in electric arc furnaces.It is both a hard and tough material with high strength, making it an excellent abrasive grain for applications. Such as grinding wheels, sandpaper, blasting media, metal preparation, lapping, polishing, and grinding. Its thermal properties make it an excellent raw material for refractory applications.
