Title:
Pt ALLOY FOR JEWELRY
Document Type and Number:
WIPO Patent Application WO/2016/208091
Kind Code:
A1
Abstract:
Because high quality alloys are preferred in jewelry items made of a Pt alloy, alloys containing 95 mass% of Pt (Pt950) are required, but Pt950 alloys exhibit low hardness, and therefore suffer from problems such as being easily damaged or deformed during use. Such problems can be solved by using a Pt alloy for jewelry which contains 0.5-4.5 mass% of Ga and 0.5-3.5 mass% of In, with the remainder comprising 95 mass% of Pt.
