Abstract

PURPOSE: To obtain the platimum alloy for decoration comprising Pt, Pd, Co and Zr or Ti in a prescribed weight composition and having excellent workability as well as excellent mechanical strength and castability.
CONSTITUTION: Platinum alloy for decoration comprising 84W96wt% Pt, 1W 15wt% Pd, 1W5wt% Co and 1.5W6wt% Zr or 1.5W6wt% Ti. Of the above-mentioned composition, in particular co is added because it meets the conditions that it does not deteriorate the workability as a material for decoration, it does not react with a casting mold in casting and it can restrain the concentration of exygen in casting and because it can improve the mechanical strength and castability. The platinum alloy for decoration thus prepared has superior hardness after annealing and an extremely excellent reproducibility for fine patterns of a casting mold in casting as conpared with the conventional platinum alloys for decoration.
