BROWN ALUMINUM OXIDE GRITS FOR BONDED ABRASIVES
Brown aluminum oxide also called Brown fused alumina, Brown corundum, BFA, etc., is a kindly of artificial corundum, HS code: 2818101000
It is made of high-quality bauxite as main raw material, fusing and purifying in a tilting electric arc furnace at high temperature of over 2200°c, and then shaped into different grain size through process of crystal, choosing, crushing, magnetic separation, air cleaning, and screening.
Main chemical composition is Al2O3 95% Min. and small quantity of TiO2, Fe2O3, SiO2, etc. It has characteristics of high hardness, great toughness, self-sharpness and good grinding performance.
By Al2O3:
