95% Abrasive Raw Materials Brown Fused Alumina grains for grinding wheel
Phoenix Abrasives Co., Limited was founded in 1999, specifized in produdtion of brown/white fused alumina, black/green silicon carbide Mainly used for sandblasting,abrasive tool,refractory,foundry industry. We own our own science management system and perfect quality control system such as omec particle size analyser, slap-sieve ,Japan SHIMADZU spectrometer and so on.
Brown Fused Alumina(BFA) is also called brown aluminum oxide (brown corundum, silicon carbide) , is made from calcined bauxite. It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded and coated products. These grains are also used for shot blasting and as polishing media. Refractory grade BFA is used as a raw material in the manufacture of high alumina refractory. It is available in grit sizes as per FEPA for abrasive applications and group grits for refractory applications.
