Pink Aluminum Oxide(PA) is fused from industrial alumina in high temperature furnace, been added with the right quantity of oxidized chromium. Its hardness is close to, but toughness higher than that of White aluminum oxide.

Pink aluminum oxide (PA) is used to grind measuring and cutting tools, instruments, etc., which demand low roughness on the surface. The abrasive tools made of it feature excellent durability and high processing cleaness, which are suitable for the precision grinding of the measuring tools, lathe main shafts, instruments and apparatus parts, threading work pieces and samplers, etc.
