Brown aluminum oxide
Brown corundum abrasive is produced by fusion of bauxite in an electric arc furnace at high temperatures.Brown fused aluminum oxide is of high hardness, toughness, self-sharpening, heat resistance and chemical stability, etc.
Brown fused aluminum oxide can be used in the manufacture of Bonded abrasives, Coated Abrasives,Vitrified/Resin grinding tool, and refractory, etc.
Brown aluminum oxide sizes :
For Abrasvies: F8-F220, F230-F1200. P8-P220 or any other sizes by customer's requirement.
For Refractories: 0-1mm, 1-3mm, 3-5mm, -200 mesh, 325 mesh or any other sizes by customer's requirement.
