Abstract

The invention discloses a jewelry material anti-sweat discoloring brown 14K gold alloy and a technology thereof. The alloy is prepared from, in percentage by weight: 0.3-0.5% of a, 0.2-0.4% of Te, 1.0-1.2% of Ru, 1.5-2.0% of Hf, 16.0-20.0% of Cu, 10.0-12.0% of Ni, 58.0-59.0% of Au and the balance silver. The patent solves the problem that the performance of current K brownish red gold is deficient, and effectively breaks the development bottlenecks in the jewelry field. It can be predicted that the implementation and industrialization of the material can achieve fruitful economic gains and social benefits.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a gold alloy. Background technique [0002] Gold has extremely high stability against corrosion, good electrical and thermal conductivity. Gold also has good craftsmanship and can be easily processed into ultra-thin gold foil, micron gold wire and gold powder. Gold is easily plated on the surface of other metals and pottery and glass, and gold is easily welded and forged under certain pressure. These numerous functional properties make gold or gold alloys widely used in modern high-tech industries, such as electronic technology, communication technology, aerospace technology, chemical technology, medical technology, etc. [0003] The original function of gold was valued as a jewelry and decorative material. With the development of the times and the improvement of people's living standards, people's aesthetic concepts have also been continuously improved, and precious metal jewe...
