BROWN ALUMINUM OXIDE GRITS FOR BONDED ABRASIVES AND SANDBLAST
Brown Fused Aluminum Oxide is an extremely aggressive and hard abrasive, the fine grits 70#,80#,90#,100#,120#,150#,180#,220#, etc. is most efficient blasting media,used primarily for blasting non-ferrous surfaces where ferric contamination is a concern ,We offer the full line of brown aluminum oxides (corundum) in all China GB/T, ANSI and FEPA gradations.
* Brown Fused Aluminum Oxide abrasive is more than 95% pure aluminum oxide. Blasting with Brown Fused Aluminum Oxide will not promote ferric contamination or rust on your surface.
* Brown Fused Aluminum Oxide’s uniform particle size provides consistent coverage and surface finish, increasing production rates.
*The low friability of Brown Fused Aluminum Oxide allows it to be recycled up to seven times or more.
Commodity: Brown Fused Alumina
Production Type: Tilting Furnace, Barmac Crushing, Air Blow Cleaning
