Abstract

PURPOSE: To obtain the platinum alloy for decoration comprising Pt, Pd, Co and Ge or Si in a prescribed weight composition and having excellent workability as well as excellent mechanical strength and castability.
CONSTITUTION: The platinum alloy for decoration comprising 84W96wt% Pt, 1W 15wt% Pd, 1W5wt% Co and 1.5W6wt% Ge or 1.5W6wt% Si. In this platinum alloy, in particular Co is added because it meets the conditions that it does not deteriorate the workability as a material for decoration, it doen not react with a casting mold in casting and it can restrain the concentration of oxygen in casting and because it improves 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 in a casting mold in casting as compared with the Conventional platinum alloys for decoration.
