Abstract

The invention discloses a gold alloy for 22K rose gold with excellent elastic performance. The gold alloy comprises the following components of, by weight, 0.4-0.6% of Ca, 0.6-0.8% of K, 0.4-0.5% of Re, 0.2-0.4% of Ta, 1.0-1.5% of Ge, 1.2-1.4% of Ru, 2.0-4.0% of Ag, 91.0-92.0% of Au, and the balance copper. According to the gold alloy, the current situations that an existing 22K rose gold materialis insufficient in elasticity and lag in the technology are solved by the patent; through an advanced material design, the elasticity performance of the 22K rose gold is greatly improved, and meanwhile, the phenomenon that the alloy is brittle after the alloy is used at a low temperature is further solved; and the implementation and industrialization of the material is expected to obtain good economic 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 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 ...
