Abstract

The invention discloses corrosion and oxidation resistant jewelry 10K green gold and a processing process for the corrosion and oxidation resistant jewelry 10K green gold. In percentage by weight, thealloy comprises the ingredients of 1.0-1.4% of Li, 2.0-4.0% of Mn, 4.0-6.0% of Fe, 8.0-12.0% of Cd, 6.0-8.0% of Zn, 15.0-20.0% of In, 40.0-42.0% of Au and the balance tin. By means of the corrosion and oxidation resistant jewelry 10K green gold and the processing process for the corrosion and oxidation resistant jewelry 10K green gold, the problems that present green K gold is seriously insufficient in corrosion resistance and generates corrosion spots after being used for 6 months are solved, the corrosion and oxidation resistant jewelry 10K green gold effectively breaks through the bottleneck of development in the field of jewelry, and prediction can be performed, implementation and industrialization of the corrosion and oxidation resistant jewelry 10K green gold will obtain fruitful economic results 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 symbol of nobility and wealth. Gold jewelry itself has infinite beauty, can play the role of decoration and enhancement, and enhance the charm and confidence of the wearer. With the development of China's economy, the domestic gold and jewelry market has gradually prospered. From the initial dominance of the world by gold jewelry, to the addition of diamond and platinum jewelry in the 1990s, the domestic gold jewelry market has basically formed a three-point pattern. Traditional gold products are increasingly unable to meet the increasing consumer demand, and gold deep processing has become the only way for many companies to capture the market. [0003] When other elements are added to gold to form a gold alloy, the resulting alloy jewelry is called K gold in the market. When gold is fused with other metals, K gold of differ...
