W40即320目棕剛玉微粉
棕剛玉是以鋁礬土、焦碳（無煙煤）為主要原料，在電弧爐內(nèi)經(jīng)高溫冶煉而成。主要化學(xué)成份為AL2O3、TiO2還含有少量的Sio2和Fe2O3等，顯微硬度HV1800-2200、韌性比SiC高，用它制成的磨具,適用于削抗張強(qiáng)度較高的金屬，如通用鋼材、可鍛鐵、硬青銅等。也可制造耐火材料。
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.
