Pink Aluminium Oxide

Pink Aluminium Oxides are an ultrapure product and most important specification is having excellent cutting quality. Chrome oxide in the content of pink aluminium oxides, is a higher level compact material according to white aluminum oxide.

Abrasive stones for grinding stones produced with pink aluminium oxide provide the best processing results. These products aggressive abrasive used in grinding application of many precision parts such as metrological equipment, motor shafts, precision machine parts, in case of precision mould cleaning to be forefront and in special blasting applications.

Pink Aluminium Oxides are one of most available material for wet and dry blasting applications and most common used material on surface treatment application and abrasive production.
