Brown Fused Alumina (For Refractory and Abrasive using).
Brown Fused Alumina is fusing under the high temperature of above 2250°C with high quality abrasive bauxite as raw material. It is characterized by good self-sharpening and high grinding ability. Brown Fused Alumina can produce ceramic grinding wheel ,resinoid grinding wheel. And BFA could be used for abrasive、sandblasting and precision casting.
