Brown Fused Alumina
Brown fused alumina, with high quality bauxite as main material, features micro-hardness and is tougher than silicon carbide. It is suitable for the normal grinding, cutting-off and loose grain polishing of metal materials with high tensile strength, such as carbon steel, alloy steel, malleable cast iron and hard bronze. It is also a very practical advanced refractory material.
