Brown Aluminum Oxide By Gongyi Baike Water Treatment Materials Co., Ltd

These Brown Aluminum Oxide is made mainly from bauxite, carbon materials and iron filings, smelting by high temperatures in electric spark furances. Brown emery is the main chemical ingredient Al2O3, its content is between 94.5% and 97%, and the other containing a small amount of Fe, Si, Ti and so on. Its micro-hardness is HV 1800-2200. Its tenacity is higher than that SiC.
Due to high temperature resistance, wear- resistance, high hardness and so on. It is available for abrasives grinding, polishing, sand blasting, precision casting and so on, and also can be used to manufacture high-grade refractory material.
