Abstract
Alloys and dental copings or abutments formed of alloys include 50-60 wt % gold, 5-14 wt % platinum, 0.1-3.0 wt % iridium and the remainder palladium. Other alloys and dental copings or abutments formed of alloys include 58 wt % gold, 10 wt % platinum, 1.0 wt % iridium, and 31 wt % palladium. The alloys are capable of withstanding temperature profiles during casting and multiple high temperature exposures of porcelain firing without excessive softening. The alloys also exhibit advantageous shear strain properties giving the alloys improved manufacturability characteristics.
