铬刚玉厂家供应铬刚玉F12-320#
铬刚玉F12-320#是以氧化铝为主要原料，适配氧化铬等。经高温熔炼而成。呈粉红色、硬度与白刚玉近似，韧性比白刚玉高。
铬刚玉F12-320#主要特性：
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，用于制造的磨具，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磨削。
Its main material is bayer alumina ,which is electrically fusd in high temperature,being added with the right quantity of oxidized chromium . The color is pink ,the hardness is close to WFA but the toughness is higher than WFA. The abrasive tools made of it feature excellent durability and high processing cleanness,which are suitable for the precision grinding of the measuring rools,lathe main shafts,instruments and apparatus parts,threading workpieces and samplers etc.
