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.
We also have Barmac equipment for mill of Brown Fused Aluminium Oxide to improve its shape by centrifugal force. BFA milled by Barmac equipment is granted more round shape grits and higher bulk density. Abrasive tools made of it is more tough, abrasion-resistant and self-sharpening. If used for sand-blasting, Barmac BFA can be recycled more times.
