Abstract

The invention discloses a jewelry material platinum alloy with martensite phase transformation characteristics and a process. The platinum alloy comprises, by weight, 0.5-1.2% of Mn, 0.4-0.5% of Ga, 4.0-6.0% of Ni, 0.1-0.3% of Hf, 5.0-10.0%fo In, 1.0-2.0% of Provided, 0.1-0.2% of Os, 10.0-15.0% of Au, and the balance platinum. Through the jewelry material, a kind of platinum alloy with the spot effect can be provided for the jewelry industry, that is, the incident light diffraction effect caused by the relief and fine layer storage in the martensite phase transformation process can be formed on the surface of the alloy. Except that the bright-colored appearance can be formed and the alloy can meet the requirement for the platinum alloy for high-end jewelries, the great social value and economic value can be obtained.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a platinum alloy. Background technique [0002] Platinum and its alloys are widely used in jewelry, handicrafts, dental materials, tableware and currency. In industry, platinum alloys can also be used as electrical contact materials and medical device materials. Jewelry made of platinum alloy has a very beautiful and elegant tone, compared to K gold. Because of its elegant style and advantages of value preservation, it is deeply loved by people. In China, especially for ethnic minorities' daily wear or festival decoration, the demand is very large. In recent years, with the improvement of people's living standards, the market demand for platinum alloys for jewelry has expanded rapidly, which indirectly shows the important position of platinum alloys in the field of jewelry. [0003] At present, many kinds of platinum alloys for jewelry have been developed at home and abroad. ...
