ABSTRACT:
Cast alloys which should be suited for both the production of removable dental construction (model casting technique) and also for permanent crowns and bridges with ceramic facing (firing technique) must combine good firing properties and good tensile strength and strain values. Alloys of this type consist of 65-85% Pd, 0-10% Au and/or 0-5% Pt, 0.1-10% Sn, 1-10% Ga, 1-12% Cu as well as 0.5-1.5 Ru and/or 0.05-0.7% Re.
