Pink fused alumina
Pink fused alumina for abrasive. Chromium Alumina . The chemical components is mainly fused Al2O3.
The main component of this material is aluminum oxide, which is electrically fused in high temperatur. And the proper quantity of Chromium Oxide is being added , so it is pink color. Its hardness is close to white alumina, but the toughness is higher than that of WA.
It can be used for polishing, grinding and making abrasive tools. Especially, it is very suitable for the precision grinding of the metering tools, lathe's main instuments and apparatus parts, threading workpieces and samples,etc.
