Brown Fused Alumina short for BFA, HS Code 28181010, CAS No. 1344-28-1, also known as brown fused aluminum oxide, brown aluminum oxide, and brown corundum is fused and crystallized under the high temperature of above 2250c with high quality abrasive bauxite as raw material and matched by the carbon material and scrap iron. It is characterized by good self-sharpening and high grinding ability. Brown Fused Alumina can be used in ceramic resin abrasive, sand blasting, grinding and polishing, and widely used in non-slip wear runway into a high-temperature basic plating, metallurgical and chemical industries of advanced refractory, the idea martial for sandblasting, cleaning parts, polishing and so on.
