PINK FUSED ALUMINA
Code: RWPA
It is electrically fused by aluminium oxide powder and chromic oxide in high temperature, Its hardness is close to, but toughness higher than that of white fused alumina. The abrasive tools made of it feature excellent instruments and apparatus parts, threading workpieces and samplers, etc.
