鉻剛玉,鉻剛玉磨料,鉻鋼玉微粉(PA)
PINK FUSED ALUMINA(PA)
鉻鋼玉，鉻剛玉微粉是以氧化鋁粉主要原料，適配氧化鉻等，經(jīng)高溫熔煉而成。鉻剛玉呈粉紅色，硬度與白剛玉近似，韌性比白剛玉高。用鉻剛玉制造的磨具，耐用度好，磨加工光潔度高。適用于量具、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 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.
