Pink Fused Alumina is produced by doping Chromia into Alumina, which gives the material pink color. The incorporation of the Cr2O3 into the AI2O3 crystal lattice produces a slight increase in toughness and a reduced friability compared with white Fused Alumina.
Description of Pink Fused Aluminum Abrasives
Pink Fused Alumina and Ruby Fused Alumina is produced by adding chromium oxide to high purity aluminum oxide during the fusion process. The amount of chromium oxide added affects the color of the final product, as well as the toughness of the grain. With increased additions of chromium oxide, the toughness of the grain increases. Compared to Brown Regular Aluminum Oxide the Pink material is harder, more aggressive and has better cutting ability. The grain shape of Pink Aluminum Oxide is sharp and angular.
Pink Fused Alumina is White Fused Alumina with chrome oxide (under 0.5% Cr2O3) has been added in the fusion process to produce a grain that is slightly tougher than regular white fused alumina used for grinding unhardened high alloy steels. If more chrome oxide (about 3% Cr2O3) has been added to, it will get Ruby Fused Alumina, which provides additional toughness over pink fused alumina.
The raw material and refining work of pink aluminum oxide are basically the same as white aluminum oxide. They are both needed to add Cr203 and well mixed to be refined as abrasives with rose red color. Its hardness is close to white corundum, and the roughness is higher than white aluminum oxide. It is suitable for grinding knifes, measuring tools, meters, screw etc. that require low roughness.
