| 白刚玉5-8mm | 白刚玉1-3mm |
白刚玉是以优质铝氧化粉为原料，经电熔提炼结晶而成， 纯度高、自锐性好、耐酸碱腐蚀、耐高温、热态性能稳定它硬度略高于棕刚玉，韧性稍低，纯度高、自锐性好、磨削能力强、发热量小、效率高、耐酸碱腐蚀、耐高温热稳定性好。用其制成磨具，适用于磨削高碳钢、高速钢及不锈钢等细粒度磨料还可以用于精密铸造和耐火材料。
White fused alumina was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.、

棕刚玉是以铝矾土、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，适于磨削抗张较高（钢材、可锻铸铁、应青铜等）的金属，适用于制造陶瓷、树脂高固结磨具以及研磨、抛光、喷砂、精密铸造等，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 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.
