F180 Brown Fused Alumina/Aluminium Oxide for Sand Blasting

F180 Brown Fused Alumina/Aluminium Oxide for Sand Blasting
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) , It 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.
