Abstract

The invention discloses an 18K rose gold alloy with excellent elasticity performance. The alloy comprises components including, by weight percent, 0.2 wt.%-0.3 wt.% of Ba, 1.0 wt.%-1.4 wt.% of Li, 0.8wt.%-1.0 wt.% of Os, 0.2 wt.%-0.5 wt.% of W, 2.0 wt.%-3.5 wt.% of Sn, 1.0 wt.%-1.8 wt.% of Co, 10.0 wt.%-15.0 wt.% of Ag, 74.0 wt.%-76.0 wt.% of Au and the balance Cu. The 18K rose gold alloy avoidsthe current situation that current 18K rose gold materials are insufficient in elasticity, and the technology falls behind. Through the advanced material design, the elasticity performance of the 18Krose gold is greatly improved, and the phenomenon of brittle failures of the alloy after usage at the low temperature is avoided. It can be predicted that rich economic gains and social benefits can be achieved due to material implementing and industrialization.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a gold alloy. Background technique [0002] Gold is a precious metal and one of the earliest metals discovered and developed by human beings. It is an important raw material for making jewelry and coins, and it is also an important reserve material of the country. It is known as the king of metals. It is not only regarded as a symbol of beauty and wealth, but also benefits human life with its unique value. An important application field of gold is decorative materials, including jewelry and so on. Gold can also be used in daily necessities, such as gold-plated clocks, belt buckles, lighters, pens, etc. Watch Kingdom Switzerland is not a big country, but its jewelry industry consumes about 40 tons of gold every year, 95% of which are used in watchmaking. Only one watch factory in Japan consumes 1 ton of gold salt a year, equivalent to 680 kilograms of gold. The use of gold is ...
