Description

GNPGraystar’s Pink and Ruby Fused Aluminum Oxide contain chromium oxide, which gives the material its Pink and Ruby color. The incorporation of the Cr₂O₃ into the Al₂O₃ crystal lattice produces an increase in toughness and a reduced friability compared with White Fused Alumina.

Compared to Brown Aluminum Oxide the Pink & Ruby materials are harder, more aggressive and have better cutting ability. The grain shape of Pink & Ruby Aluminum Oxide is sharp and angular.

Application areas

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. These are 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.
