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 with metrology instruments, engine crankshafts, instrument parts, threads and samplers.

The FEPA F grades are especially suitable for the manufacture of
vitrified bonded 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 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.
