Abstract

PURPOSE: To enhance the workability, corrosion resistance and castability of a platinum alloy for decoration as compared to a conventional one by adding Co 1W 15% to a Pt-Pd alloy or further adding Y 0.01W3W/O.
CONSTITUTION: The reason why Co is added to the platinum alloy for decoration is to enhance the mechanical strength and castability of the alloy. Co<1W/O is not enough to enhance the mechanical strength and castability, and Co>15W/O remarkably deteriorates the workability, so Co is added in an amt. of 1W15W/O. Y is added to further enhance the mechanical strength owing to grain refining as well as to further enhance the castability. Y<0.01W/O slightly improve the castability, and Y>3W/O deteriorates the workability. The Co and Y-added platinum alloy is an epoch-making alloy which can be used in place of a conventional platinum alloy for decoration.
