Pink Aluminium Oxide or Ruby Aluminium oxide is electrically fused in high temperature, being added with the right quantity of oxidized chromium. It is pink. Its hardness is close to WA, but toughness is higher than WA.
The abrasive tools made of it feature excellent durability and high processing cleanness, which are suitable for the precision grinding of the measuring tolls, lathe main shafts, instruments and apparatus parts, threading work pieces and samplers, etc.
The PA or RA can also be used in coated abrasives. It is mainly used for sanding wood. It is also used for sanding ferrous metal, such as copper, brass, etc. Compared to white aluminium oxide, PA and RA are more non-breakable. So, smooth surface is easy to get.
