Huilian Brown Alumina of high content of Al2O3 selling well in 2011
Brown corundum is made mainly from bauxite, carbon materials and iron filings, smelting by high temperature in electric spark furances. Al2O3 is the main chemical ingredient of Brown fused aumina, 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. The abrasive tools made of it are fit grind materials of all kinds, such as universal steel and general alloy stell. It can be used to forge rough iron and hard bronze and make advanced refractory.

Usaging
a. As there is high temperature, corrosion resistance, high strength properties, it is available for making abrasive bands and emery cloths, it poured with steel sliding gate, smelting rare metals, special alloys, ceramics, iron-smelting furnace of the lining (walls and tubes); physical and chemical containers , spark plugs, heat-resistant anti-oxidation coating.
b. Due to high hardness, wear resistance, high strength characteristics, in the chemical system, used for a variety of reaction vessels and pipelines, chemical pump parts; to do mechanical parts, various molds, such as the Roberts mold, extrusion die nozzle pencil lead, etc.; do tool, die grinding, bullet-proof material, the human body joints, sealing ring mold.
