Abstract

The present invention relates to a metal alloy with by weight from about 95% to about 99% platinum metal, about 1.5% to about 4% of a group IB metal, and about 0.001% to about 5% of an additional alloying element selected from the group consisting of: iron, nickel, and a combination of iron and nickel. Preferably, the metal alloy consists of about 95% to about 99% platinum, about 1.5% to about 4% of silver, and about 0.001% to about 5% iron meteorite. The metal alloy has improved castability, resistance to porosity, resistance to shrinkage, pitting and cracking when worked, ductility, soldering properties (thermal conductivity and heat capacity), remelting, electrical conductivity.
