Addition of chrome oxide to Calcined Alumina gives Pink Fused Alumina (Pink FA). It is not as friable as WFA. It is used in the manufacture of special types of grinding wheels.

Pink aluminium oxide abrasive is electrically fused from alumina and other materials. The pink colored abrasives has hardness similar and toughness greater than white aluminum oxide. Grinding wheels made of pink aluminum oxide have the features of outstanding durability and producing fine surface finish. Suitable for precision grinding applications...more

DETAILS Introduction: Pink Fused Alumina is made from high quality bayer-processed alumina by fusing in an electric arc furnace at high temperature, being added with the right quantity of oxidized chromium. Characters: It is pink, its hardness is close to, but toughness is higher than WA. Application: The abrasive tools made of it feature ...more
