Brown Fused Alumina

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