Abstract

PURPOSE: To provide a 9- or 10-carat gold alloy for decoration free from discoloration due to oxidation without a protective plated layer and maintaining the golden luster over a long term by alloying Au with Ag, Cu, Zn, etc. in a specified ratio.
CONSTITUTION: The 9- or 10-carat Au alloy is composed of, by wt., Au 37.5W 41.7% and alloying metal 62.5W58.3%, and the compsn. of the metal consists of, by wt., CU 75.7W76.7%, Ag 14.2W15.5% and Zn 7.8W10.1%. 1W5wt% of Pt, Pd, Ru, Sn or a mixt. thereof may be added and alloyed. The Au content of this alloy is low, and this alloy does not undergo a change in the golden color due to oxidation over a long term, so it is utilized as a material for accessories such as a necklace and a pendant.
