Metallographic Grinding And Polishing Insight

Aluminium oxide, with a hardness of about 2,000 HV, is primarily used as an abrasive in grinding stones. It is mainly used for the preparation of ferrous metals. It was also extensively used as a polishing medium, but since the introduction of diamond products for this purpose, it has largely lost its usefulness in this application.
