What is the brown fused alumina(BFA)/browen corundum powder?
1. Brown Fused Alumina (BFA) is produced by a reduction fusion of high quality bauxites in electric arc furnaces at temperatures greater than 2000°.
2. Brown Fused Alumina (BFA) is both a hard and tough material with high strength.
3. Brown Fused Alumina (BFA) is an excellent abrasive grain for applications such as grinding wheels,sandpaper, lapping, polishing, and grinding etc.
4. Brown Fused Alumina (BFA) is also an excellent raw material for refractory applications.
