Pink corundum is produced by doping Chromic 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 corundum.The abrasive tools made of it feature excellent durability and high processing cleanness, which are suitable for the precision grinding of the measuring tolls, lathe main shafts, instruments and apparatus parts, threading work pieces and samplers, etc.
▼Applications:
●Suitable for the manufacturing vitrified bonded abrasives for working hardened steels and alloys with tensile strengths of over 50 kg/mm².
●Used in tool grinding, knife-sharpening applications, precision grinding, profile grinding, flute grinding, tooth grinding, dry grinding of blade segments and mounted wheels.
●A preferred material for working non-ferrous metals and the alloys (copper, aluminum, zinc, brass, Bronze),
●Used for softer materials, such as wood, synthetics and paints
Compared to Brown Regular Aluminum Oxide the Pink Fused Alumina is harder, more aggressive and has better cutting ability. The grain shape of Pink Fused Alumina is sharp and angular.
