Pink Aluminum Oxide's main element is bayer Alumina, which is electrically fused under high temperature, with the right quantity of oxidized chromium. It is pink. Its hardness is close to, but toughness is higher than that of WA. The abrasive tools made of it are featured with 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.
