Abstract

PURPOSE: The platinum alloy comprising Pt, Pd, Co and In in a specific component composition and having excellent workability, mechanical strength and castability.
CONSTITUTION: The component composition of the platinum alloy is 84W96 Pt at W/O, 1W15 Pd, 1W5 Co and 1.5W6 In. The purpose of Co addition is to prevent deterioration in workability and to eliminate a reaction with a casting mold in casting, and the reason for In addition is that In forms an intermetallic compound, In-Pt, hardening the alloy and increasing its mechanical strength.
