Pink Aluminum Oxide is produced by doping Chromic into Alumina, which gives the material pink color. 

The incorporation of the Cr2O3 into the Al2O3 crystal lattice produces a slight increase in toughness 

and a reduced friability compared with White Fused Alumina.

Compared to Brown Regular Aluminum Oxide the Pink Fused Alumina is harder, more aggressive and has better cutting ability. The grain shape of Pink Fused Alumina is sharp and angular.
