棕色氧化鋁砂
棕色氧化鋁砂簡介/Description of brown fused alumina:
棕色氧化鋁砂是以鋁礬土、無煙煤為主要原料，在2000度以上電弧爐內經高溫冶煉而成，用它制成的磨具，適於磨削抗張較高（鋼材、可鍛鑄鐵、應青銅等）的金屬，適用於制造陶瓷、樹脂高固結磨具以及研磨、拋光、噴砂、精密鑄造等，也可制造耐火材料。棕色氧化鋁砂具有純度高，結晶好，流動性強，線膨脹係數低，耐腐蝕、耐高溫、高強度等特點。
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.
