Product Description
Pink Fused Alumina ( PA ) is produced by bayer alumina and right quantity oxidized chromium in an electric arc furnace at high temperatures. Compared with white aluminium oxide, the product shows similar hardness and lower toughness. The abrasive tools which made of PA have excellent durability and high processing cleanness. The materials are used to grind measuring and cutting tools, instruments, threading workpieces, etc. which demand low roughness on the surface.
