Abstract

The invention discloses a 14K corrosion-resistant brittleness-resistant alloy with a Spangold effect and a process thereof. The 14K corrosion-resistant brittleness-resistant alloy with the Spangold effect comprises, by weight, 4.0%-6.0% of In, 5.0%-8.0% of Ni, 0.2%-0.6% of Y, 0.2%-0.5% of Ta, 2.0%-2.5% of Re, 0.1%-0.2% of Ge, 0.4%-0.8% of Cr, 58.0%-59.0% of Au, and the balance sliver. The 14K corrosion-resistant brittleness-resistant alloy has the Spangold effect and is applied to jewelry, and gold jewelry prepared from the 14K corrosion-resistant brittleness-resistant alloy has a bright colorof pearl spots. The jewelry prepared from the 14K corrosion-resistant brittleness-resistant alloy has an outstanding surface impression, the smelting and processing technique is simple, and thus, the14K corrosion-resistant brittleness-resistant alloy with the Spangold effect has great economic value while meeting the urgent demands of domestic and foreign markets in the jewelry industry.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a gold-based alloy. Background technique [0002] Pure gold has a very beautiful yellow luster and is chemically stable. It is not easy to change color when heated, that is, it has excellent anti-oxidation properties. Throughout history and consumer markets at home and abroad, gold has always been used as a jewelry material and is favored by people. With the improvement of modern consumption awareness, the patterns of jewelry made of gold are constantly being refurbished. In the past, single gold jewelry was gradually replaced by beautiful and various gold alloys. In addition to being used for jewelry, these gold alloys are also mostly used for watch cases, watch straps, spectacle frames and various handicrafts. In addition to having different colors (commonly white, yellow, red and pink), these gold alloys have good chemical stability, good surface anti-tarnish performance, a...
