Abstract

PURPOSE: The platinum alloy for decoration comprising Pt, Pd, Co and K in a specific component composition and having excellent workability, mechanical strength and castability.
CONSTITUTION: The component composition of the platinum alloy is 84W96Pt at W/O, 1W15 Pd, 1W5 Co and 1.5W6 K. The purpose of Co addition is that the addition prevents deterioration in workability and eliminates a reaction with a casting mold in casting, and the reason for the addition of K is that K forms an intermetallic compound with Pt, hardening the alloy and increasing its mechanical strength.
