Brown Aluminum Oxide P Grains Introduction

Brown Aluminum Oxide is made by electric arc furnace smelting under high temperature with the raw materials of bauxite, anthracite and scrap iron. The significant chemical composition of brown aluminum oxide is aluminum trioxide (chemical formula: AL2O3). It is characteristic by high hardness, high toughness, and high abrasion resistance.

The brown aluminum oxide P grain has more aggregative in distribution than F grain, with features of sharpness and evenly distributive, brings more efficiency for surface treatment. Brown fused aluminum oxide P grain is widely used in coated abrasive such as abrasive cloth, abrasive paper abrasive belts, etc.
