白刚玉
白刚玉是以**铝氧粉为原料,经电熔提炼结晶而成,它硬度略**棕刚玉,韧性稍低,纯度高,自锐性好,磨削能力强,发热量小,**,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,高速钢等。还可作为研磨,抛光材料,精密铸造,喷涂材料,化工触媒载体,特种陶瓷,高级耐火材料等。
Whitle aluminium oxide
White aluminium oxide is electrically fused in the furnace with high grade bayer processed alumina as raw material..It has high purity,ability of self-sharpening,better cutting,less heat emit,higher efficiency,acid and alkali resistance,good thermal  tools made of it are suitable for grinding high-speed,high carbon steel , also can be used as materialsfor grinding and polishing,precision casting,spaying and coating, medium body for chemical industry,special ceramics and high-grade refractory materials,etc.
棕刚玉
棕刚玉是以铝矾土等为原料,经高温熔炼结晶而成。它具有硬度高,韧性大,颗粒锋锐等特点。用其制成的磨具适用于磨削加工抗张强度高的金属材料。如:碳素钢,一般合金钢,可锻铸铁,硬青铜等。也可以作为耐火材料之用。
Brown aluminium oxide
Brown aluminium oxide is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its
