pink fused alumina; abrasive grain; good hardness and toughness; high alumina content; Pink Fused Alumina is produced by doping Chromia 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 with Brown Regular Aluminum Oxide,the Pink ...
