Abstract

The invention relates to the technical field of alloys and in particular relates to rose-bengal 18 K gold. The rose-bengal 18 K gold comprises the following ingredients in percentage by weight: 15.5-20.8 percent of copper, 1.5-2.8 percent of sliver, 0.11-0.25 percent of cerium, 0.13-0.21 percent of titanium, 0.04-0.16 percent of cobalt, 0.1-0.17 percent of indium, 0.1-0.5 percent of neodymium and the balance of gold and inevitable impurities. The invention further provides a synthetic method of the rose-bengal 18 K gold alloy. The rose-bengal 18 K gold alloy is good in high temperature tolerance and long in service life and resists high temperature, oxidation and creep deformation. The manufactured gold jewelry is low in price, high in hardness and lasting in color and luster and can be worn for a long term.

Description

technical field [0001] The invention relates to the field of alloys, in particular to rose red 18K gold and a preparation method thereof. Background technique [0002] Gold is easy to fall off due to insufficient strength when inlaid with gemstones. Therefore, people add silver, copper, zinc and other metals to gold to increase the strength and toughness of gold, and the K gold jewelry made in this way. Karat gold is the most commonly used and most varied material in jewelry. The relationship between K number and gold content: Au wt%=K / 24×100%. K gold can be formulated into various colors according to needs. The internationally popular K gold jewelry is available in various colors, and the common ones are yellow and white. K gold has always been a favorite jewelry material for Europeans. Colored gold jewelry is more and more popular because of its lighter weight, lower price, exquisite workmanship and novel style. K gold can be mixed with more other elements, and can be ...
