棕刚玉F150#目粒度砂

棕刚玉F150#是以铝矾土、无烟煤、铁屑作为主要原料，在电弧炉内经高温炼制而成，呈棕褐色，韧性好，显微硬度1800-2200kg/mm2,体积密度3.85g/cm3,耐高温，耐火度高达1850℃，由于它具有耐高温，强度高，抗氧化，耐侵蚀，耐磨损等优良性能，所以在耐火材料和磨料磨具行业被广泛使用，可做耐火材料和磨料。

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.
