Pink Fused Alumina

Pink Fused Alumina is produced by fusion of Calcined Alumina with addition of Chromium Oxide. The colour of the final product as well as the toughness of the grain depends on the amount of chromium added during fusion. With increased addition of Chromium, the toughness of the grain increases and friability reduces compared with White Fused Alumina. 

Application

Pink Fused Alumina are especially suitable for making Vitrified wheels and abrasives for hardened steels and alloys. It is also used in tool grinding, precision grinding, profile grinding, flute grinding, tooth grinding and mounted wheels.
