Brown fused alumina polishing
Brown aluminum oxide crystals is made of bauxite/anthracite coal, and smelted in electric-arc furnace of high temperature more than 2000degrees.Abrasives tools made by brown fused alumina are suitable for metal with high tensile (like:steel, malleable iron, bronze etc).and suitable for grinding, polishing, blasting, precision casting etc.Brown aluminum oxide crystal is also used for refractory material. Brown aluminum oxide crystals with characteristics like: high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion resistance, high temperature, high strength.

Product Description Brown Fused Alumina is fused and crystallized under the high temperature of above 2250°C with high quality bauxite, carbon and iron as raw material. Our product characterized by high purity, good crystal, strong fluidity, low coefficient of linear expansion, good corrosion-resistance and so on. Could not burst, no pulverization and crack in using course of refractory. Advantage 1. Brown corundum is characterized by high purity, dense texture, large stacking density, strong self-sharpness, good toughness and extremely low magnetic content; 2. The grinding tool made of it has the advantages of sharp grinding, low heating rate, high grinding ratio and less adhesion in use; 3.The sintered abrasive tool has the characteristics of deep blue color, no network crack and no rust spot after firing.
Brown Fused Alumina is also called Brown Corundum, it is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials.
