铬刚玉磨料

铬刚玉是以冶金级铬绿和工业氧化铝为原料，以在2000℃以上高温条件下发生化学反应，而获得高级铬钢玉。

   产品具有较好的高温热化稳定性，耐冲刷性，抗侵蚀性和耐磨性。晶体呈粉红色，硬度与白刚玉近似，韧性比白刚玉高。用铬刚玉制造的磨具，耐用度好，磨加工光洁度高。适用于量具，机床主轴，仪表零件、螺纹工件及样板磨等精密磨削。

Its main material is bayer alumina ,which is electrically fusd in high temperature,being added with the right quantity of  oxidizedomium . The colis pink ,the hardness is close to wfa but the toughness is higher than Wfa. The abrasive tools made of it feature excellent durability high processing cleanness,which are suitable fthe precision grinding of the measuring rools,lathe main shafts,instruments apparatus parts,threading workpieces samplers etc.
