棕剛玉微粉W28 棕剛玉400#目 日標(biāo)600#目

棕剛玉W28微粉是以鋁礬土、無煙煤為主要原料，在2000度以上電弧爐內(nèi)經(jīng)高溫冶煉而成，用它制成的磨具，適于磨削抗張較高（鋼材、可鍛鑄鐵、應(yīng)青銅等）的金屬，適用于制造陶瓷、樹脂高固結(jié)磨具以及研磨、拋光、噴砂、鑄造等，也可制造耐火材料。棕剛玉具有純度高，結(jié)晶好，流動(dòng)性強(qiáng)，線膨脹系數(shù)低，耐腐蝕、耐高溫、高強(qiáng)度等特點(diǎn)。

Haixu 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.
