BROWN FUSED ALUMINA

Catalog: Abrasive | 2023-10-09

Brown Fused Alumina (BFA) is produced by a reduction fusion of high quality bauxites 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.
