 Brown fused alumina is bauxite, coke (anthracite) as main raw material, high temperature smelting in electric arc furnace, the main chemical composition of Al203, Titania and also contain small amounts of Si02 and Fe203 the microhardness HVl800-2200 toughness than SiC, it is made of abrasive suitable for higher metal grinding tensile strength, such as a variety of common steel, malleable iron, hard bronze. Can also create high-grade refractory. . 
 ???? Widely used in copper alloys as well as pre-treatment in the exercise iron and hard bronze, high tensile strength metal plating, painting, Teflon, rubber coated, gold jewelry injury of aesthetic processing.
