Abstract

PURPOSE: To provide a decorative Pt alloy having excellent hardness, forging properties, and high-temperature strength by adding a specific amount of one or more of Pd, Ir, Ru, Rh, Au, Ag, Cu, Ni, and Co to an alloy essentially consisiting of Pt and contg. Misch metal.
CONSTITUTION: A Pt alloy consists of 80W95wt% of Pt, 0.01W5.0wt% of Misch metal, and 1W15wt% in total of at least one of Pd, Ir, Ru, Rh, Au, Ag, Ni, and Co. This alloy is excellent in mechanical strength, especially in hardness, and has a good flowing property in molten state. The alloy thus processed allows good reproduction of fine patterns of a cast mold no cavity in the cast, providing an extremely excellent property as a decorative platinum alloy.
