Product Detail Information

Product Description
Brown fused alumina is bauxite, coke (anthracite) in raw materials, melting in electric arc furnace at high temperature. The main chemical compositions are Al2O3, TiO2 and a little SiO2, Fe2O3 and so on. Its hardness is HV1800-2200 and it's tougher than Sic. The abrasive made from it is suitable for high tensile strength metal, such as a variety of common steel, malleable iron and hard bronze. It also can be used as advanced refractory.
The physical and chemical analysis:
