Aluminum Oxide
Brown aluminum oxide is fused in an electric arc furnace by high temperature. Its main raw materials are bauxite, anthracite. It’s chemical composition contains far over 90% Al2O3. Fused aluminum oxide abrasive grains are made for maximum toughness and hardness to provide superior performance in blasting applications from cleaning and deburring to etching and finishing.
