Product Introduction:
Brown Aluminum Oxide (BFA) is produced by smelting of calcined bauxite at more than 2000°C in an electrical furnace, and made into different grain size through crystal, choosing, crashing, magnetic separating, screening, washing, acid washing and dry cleaning etc. It has the features of high hardness and good toughness,sharp grits, no free silica when blasting, it is the environmental - friendly raw material in abrasive blasting. 

Application:
Grinding Wheels / Cutting Wheels / Cutting Discs
Sand Paper / Sand Belt
Abrasive blasting / Surface Preparation / Rust Removal
