Abstract

The invention discloses a red Hmong gold alloy of low density, high hardness, anti-corrosion, and low gold content and a process thereof. The composition of the alloy comprises by weight, 0.8-1.2wt.%of Li,10.0-18.0wt.% of Al, 6.0-8.0wt.% of Ge, 0.3-0.5wt.% of Ce, 2.0-4.0wt.% of Mn, 15.0-18.0wt.% of Sn, 14.0-16.0wt.% of Au, and the balance copper. The material provides a lightweight selection scheme for Hmong gold alloy in China; the obtained product has excellent red appearance and excellent corrosion resistance. The implementation and industrialization of the materials can effectively push the product updating of jewelry in China and industrial upgrading demands.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a gold alloy. Background technique [0002] The Miao people love silver jewelry very much, and the earliest description of the Miao people wearing silver jewelry comes from the Ming Dynasty. Today, the wearing of silver jewelry has become a materialized expression of Miao culture. The distinction between costumes and casual clothes in silver jewelry divides the sacred and secular dual spaces of the Miao people. According to the Miao people, "you can't be a girl without silver and flowers, and you can't be a dress with clothes and silver." In the grand festivals and important ceremonial occasions of the Miao nationality, silver jewelry is the admission ticket for women. There are extremely profound cultural traditions in any seemingly simple living habits. Miao costumes with silver ornaments as an important part are also called "history books worn on the body". There are also ...
