grinding wheel used Brown fused alumina of 90%Al2o3

BFA brown alumina oxide  1) High AL2O3 content: 95%min 
2) Professional manufacturer 
3) Prompt delivery Description:  Brown fused alumina(BFA) is made from Calcined Bauxite. It is 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.  Application:  Resin ceramic abrasive, sand blasting, grinding and polishing, and is widely used in anti-wear runways, high-temperature coating matrix and metallurgy, chemical industry, and other high-level furnace refractories.     Technical Data of our BFA:
