Brown Fused Alumina is fused and crystallized 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
Brown corundum abrasive has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient and corrosion resistance. The product produced by Chenhui Abrasive has the characteristics of non-explosive, non-pulverizing and non-cracking during use.
