Brown fused alumina is produced by melting and fusing from high-grade bauxite in an electric arc furnace. Its characteristics are small coefficient of expansion and strong toughness. This kind of abrasive would eliminate the cracks of the products processing and improve the grinding precision and efficiency. So it is especially fit for all kinds of advanced bonded abrasive tools and coated abrasive tools.
