BFA Brown Fused Alumina powder in refractory Brown corundum micro powder 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.Its thermal properties make it an excellent raw material for abrasive and refractory applications. Advantages Of Brown Corundum Powder: 1. Large crystal, high strength, good toughness, dense texture, high bulk density. 2. Stable performance between batches. 3. The higher grinding efficiency and polishing brightness, the grinding efficiency is much higher than the soft abrasives such as silica. 4. Good particle appearance, high surface finish of the polished object.
