一級人造磨料粒度砂60#鉻剛玉60目鉻剛玉
60目鉻剛玉：
鉻剛玉是以氧化鋁為主要原料，適配氧化鉻等。經高溫熔煉而成。呈粉紅色、硬度與白剛玉近似，韌性比白剛玉高。
60目鉻剛玉特性：
產品具有較好的高溫熱化穩定性，耐衝刷性，抗侵蝕性和耐磨性。晶體呈粉紅色，用於制造的磨具，度好，磨加工光潔度高。適用於量具，機床主軸，儀表零件、螺紋工件及樣板磨等精密磨削。
Its main material is bayer alumina ,which is electrically fusd in high temperature,being added with the right quantity of 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.
