Abstract

The invention discloses a gold alloy. The gold alloy is prepared from the following components: 58.5%-62.5% of Au, 18.2%-21.9% of Ag, 6.1%-8.5% of Cu, 3.8%-6.0% of Pt, 2.2%-4.1% of Fe, 1.5%-2.5% of La, 1.3%-2.5% of Cr and 0.7%-1.5% of Mn. The gold alloy reaches the standard of 14K gold and can be suitable for manufacturing a spring used in precious jewelry. The invention further discloses a methodfor manufacturing the spring using the gold alloy and the spring prepared by the method. The spring has suitable elasticity and can be used in the precious jewelry.

Description

technical field [0001] The invention relates to the technical field of alloys, and more specifically, to a gold alloy, a method for making a spring by using the gold alloy, and the prepared spring. Background technique [0002] Gold jewelry refers to jewelry made of gold as the main raw material. It has a very beautiful and bright yellow luster, and has good chemical stability. It is not easy to change the color when heated. It has the functions of decoration and value preservation, and is favored by people. . With the further development of my country's economy, the improvement of modern consumption awareness, and the continuous renovation of gold jewelry styles, people's demand for gold jewelry is becoming more and more vigorous. [0003] Gold jewelry can be divided into pure gold and K gold in terms of its gold content. The gold content of pure gold jewelry is required to be more than 99%, up to 99.99%, so it is also known as "ninety-nine gold", "full gold" and "red gol...
