Pink - Ruby Fused Alumina

Pink and Ruby Fused Alumina is produced by adding chromium oxide to high purity aluminum oxide during the fusion process. The amount of chromium oxide added affects the color of the final product, as well as the toughness of the grain. With increased additions of chromium oxide, the toughness of the grain increases.

RU and RUHC are used in vitrified griding wheels, coated abrasives, blasting abrasives, and other applications. See below for product information relating to your application.

Pink & Ruby Fused Alumina

RU - Pink Fused Alumina - Bonded & Industrial Abrasives

RU - R is a pink aluminum oxide obtained by fusion of calcined alumina and chrome ore in electric arc furnaces. Its high purity and self-edged reposition characteristic makes RU a special product for vitrified grinding wheels.

RU - Pink Fused Alumina - Coated Abrasives

RU - L is a pink aluminum oxide obtained by fusion of calcined alumina and chrome ore in electric arc furnaces. Its high purity and self-edged reposition characteristic makes RU a product for special applications where contamination is an issue to be considered.

RUHC - Ruby Fused Alumina - Bonded & Industrial Abrasives

RUHC - R is a dark pink aluminum oxide obtained by fusion of calcined alumina and chrome ore in electric arc furnaces. Its high purity and self-edged reposition characteristics make RUHC a special product for vitrified grinding wheels.
