Pink Fused Alumina, also called Pink Fused Aluminum Oxide, Chromium Aluminum Oxide, or ruby fused alumina, abbreviated as "PA".It is obtained by adding chromium oxide to high purity aluminum oxide during the fusion process. Its color is pink and ruby. The content of chromium oxide added affects the color of the final product. With increased additions of chromium oxide, the toughness of the grain increases. our factory can produce pink fused alumina (PA) and ruby fused alumina (RA), and our PA and RA have the features of good crystallinity, pure color, less impurity, well-distributed particle size composition, low magnetic substance content, high bulk density, high toughness.
Pink aluminum oxide is exceptional for the manufacturing of vitrified bonded abrasives allowing for grinding on hardened steels and alloys with high tensile strength. Pink aluminum oxide is mostly used for grinding and sharpening applications. Pink aluminum oxide can be used on non-ferrous metals, aluminum, zinc, brass, bronze, copper, wood, synthetics, and paints.
