Sandblasting material brown corundum

Brown corundum 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.

▼Usage:
Ceramic resin abrasive, sand blasting, grinding and polishing, and widely used in non-slip wear runway into a high-temperature basic plating, metallurgical and chemical industries of advanced refractory ,the idea martial for sandblasting, cleaning parts, polishing and so on.
