Brown corundum refractory aggregate abrasives:                                                                                                                

Brown corundum refractory aggregate abrasives 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.
