棕刚玉Brown Fused Alumina

棕刚玉是以铝矾土、无烟煤为主要原料，在2000度以上电弧炉内经高温冶炼而成，用它制成的磨具，适于磨削抗张较高（钢材、可锻铸铁、应青铜等）的金属，适用于制造陶瓷、树脂高固结磨具以及研磨、抛光、喷砂、铸造等，也可制造耐火材料。棕刚玉具有纯度高，结晶好，流动性强，线膨胀系数低，耐腐蚀、耐高温、高强度等特点。

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 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. 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.
