BROWN ALUMINUM OXIDE
Brown aluminium oxide abrasive electrically fused in an arc furnace from amixture of bauxite at high temperatue. It has brown coloue high hardness and great toughness. The abrasive tools made by brown fusedalumininm oxide are suitable forgrinding carbon stell. normal alloy sfell malleable cast iron and hard buonze. Tt uesd for refractory aluminum Oxide lining mixture pouring materials castable etc.
