What is the Definition of Pink Fused Alumina?

Pink Fused Alumina is White Fused Alumina with chrome oxide (<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.

Pink fused alumina is suitable for manufacturing vitrified abrasives for working hardened steels and alloys with tensile strengths of over 50 kg/mm². It is also used in tool grinding, saw and knife-sharpening applications, precision grinding, profile grinding, flute grinding, tooth grinding, dry grinding of blade segments and mounted points/ wheels.
