PROCESS OF PRODUCTION AND CHARACTER

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 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.

Applications

The FEPA F grades are especially suitable for the manufacturing vitrified bonded abrasives for working hardened steels and alloys with tensile strengths of over 50 kg/mm². It is also used in tool grinding, knife-sharpening applications, precision grinding, profile grinding, flute grinding, tooth grinding, dry grinding of blade segments and mounted wheels.

The FEPA P grades are a preferred material for working non-ferrous metals and the alloys (copper, aluminum, zinc, brass, Bronze), but also used for softer materials, such as wood, synthetics and paints.
