PINK FUSED ALUMINA


Pink Fused Alumina is produced by adding chromium oxide to high purity aluminum oxide during the fusing 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.

Suntek Material’s Pink Fused Alumina is used in vitrified grinding wheels, coated abrasives, blasting abrasives and other applications.
