Abstract

The invention discloses a brown corrosion-resistance and brittleness-resistance high-strength 10 K gold alloy and a process thereof. The alloy comprises the following components in percentage by weight: 0.3-0.5 wt.% of Sr, 0.2-0.4 wt.% of P, 1.5-1.8 wt.% of Rh, 1.2-1.6 wt.% of V, 15.0-18.0 wt.% of Cu, 20.0-22.0 wt.% of Co, 41.0-42.0 wt.% of Au, and the balance of silver. The alloy solves the current situation of insufficient performances of traditional K brownish red gold, and effectively breaks through the development bottleneck in the jewelry field. The implementation and the industrialization of the material can be estimated to achieve plenteous economic gain and social benefit.

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...
