铬刚玉,铬刚玉磨料,铬钢玉微粉(PA)PINK FUSED ALUMINA(PA)铬钢玉，铬刚玉微粉是以氧化铝粉主要原料，适配氧化铬等，经高温熔炼而成。铬刚玉呈粉红色，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 fused in high temperature,being added with the right quantity of oxidized chromium.It is pink.Its hardness is close to,but toughness higher than that of WA.the abrasive toola made of it feature excellent durability and high processing cleanness,which are suitable for the precision grinding of the measuring tools,lathe main shafts,instruments and apparatus parts,threading workpieces and samplers,etc.
