Brown aluminum oxide abrasive fused alumina refractories hardware is electrically fused in 

an arc furnace from a mixture of bauxite at high temperature. It has brown colour, high hardness and

 great toughness. The abrasives tools made of brown aluminum oxide are suitable for steel, malleable

 cast iron and hard bronze. It used for refractory aluminum oxide lining mixture, pouring materials castable, etc.
