Pink fused alumina is an aluminum oxide that during the furnace process had chromium oxide added. According to the chromium content, the color of chrome fused alumina shows pink or ruby. The incorporation of the Cr2O3 into the Al2O3 crystal structure slightly increases the toughness of the grain while reducing the friability in comparison to white fused alumina. In comparison to brown fused alumina, pink fused alumina is harder, more aggressive, and has sharper cutting ability.
