二级三级喷砂棕刚玉人造磨料 电熔棕刚玉 F30#棕刚玉

棕刚玉是以铝矾土、*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 i*ade of bauxite/anthracite coal, and *elted in electric-arc furnace of high temperature more than 2000 degrees. Abrasives tool*ade by brown fused alumina are suitable for metal with high tensile(like: steel, malleable iron, bronze etc). Suitable for product high c*olidation abrasive, and suitable for grinding, polishin*asting, precision casting etc. brown fused alumina is also used for refractory material. Brown fused alumina with characteristics like: high purity, good crystalline liquidity, low coefficie*f linear expansion, corrosion resistance, high temperature, high strength.
