Brown Fused Aluminium Oxide(Brown Fused Alumina),abbreviated as BFA, is made according to FEPA, JIS
Standard etc with fine particle distribution for bonded abrasives, sand blasting and surface treatment. Because of its
hardness, toughness, sharp edge and self-sharpening character, Brown Fused Aluminium Oxide is an ideal
synthetic abrasives material for production of abrasive tools(Bonded Abrasive Grinding Wheels, Cutting Discs,
Mounted Heads etc, and also in Sand Blasting and Polishing purposes. Brown Fused Aluminium Oxide is the most
used abrasives because of its features and cost. Our BFA FEPA grits are with about 95%min Aluminium
Oxide(Al2O3), high purity, coarse particles, low magnetic contents, high cleanliness.
