Tilting Furnace Pink Fused Alumina Angular Shape 97.5% For Vitrified Abrasives
Tilting Furnace Barmac Crushed Pink Fused Alumina for Vitrified Abrasives
1. Pink Fused Alumina Introduction
Pink Fused Alumina is White Fused Alumina with chrome oxide (<0.5% Cr2O3) has been added in the fusion process to produce a grain that is slightly tougher than regular white fused alumina used for grinding unhardened high alloy steels. Pink aluminum oxide isobtained 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.
