Palladium-based ternary or higher alloys

Abstract

An example palladium-based alloy includes a palladium-copper-silver alloy. Such an alloy may include palladium at about 50-57 weight percent (“wt %”), copper at about 35-42 wt %, and silver at about 3-7 wt %. The alloy may also include at least one of rhenium, zinc, gallium, indium, or any of the other elements disclosed herein. For instance, the alloy may include at least 0.5-2 wt % of at least one of rhenium, zinc, gallium, or indium. The alloy may exhibit at least one of a conductivity of 28% of the international annealed copper standard for electrical conductivity or greater, an ultimate tensile strength of 1.1 GPa or greater, a yield strength of about 825 MPa or greater, or a current that may be carried by a 250 μm wire of about 4 A or greater.
