Cromo-Cobalto F75



Cromo-Cobalto

Il Cromo-Cobalto è una superlega caratterizzata da eccellenti proprietà meccaniche (resistenza, durezza, ecc.), resistenza alla corrosione ed alle alte temperature. Tali leghe sono comunemente utilizzate in ambito biomedicale e dentale, innesti medici ed anche per applicazioni ingegneristiche ad alta temperatura come i motori aeronautici. I pezzi costruiti con questo materiale sono privi di nichel (<0,1%), sterilizzabili ed adatti alle applicazioni biomediche. Sono caratterizzati da una struttura sottile ed uniforme.
