Pink Aluminum Oxide

Product Detail

Instruction:

Pink fused alumina looks pink, because is electrically fused in high temperature, being added with the right quantity of oxidized chromium. Its hardness is close to, but toughness higher than that of WA.

It's an abrasive material with moderate friability, recommended for tool and internal grinding, grinding jobs in instrument industry. It's also suitable for various grinding purpose with high surface finish.
