Problems solved by technology

[0007] However, it must be noted that although my country's jewelry industry, especially gold alloys for jewelry, has developed rapidly, due to its late start and low starting point, there is still a big gap compared with the international level in some technical links.
The long-term unsolved problems in the industry not only affect the market sales and user experience of related products, but also seriously limit the market share of such products in the international field
The development and industrialization of rose-colored silver alloys is already an inevitable problem in the field of jewelry. For a long time, many domestic research institutions and enterprises have made multi-faceted attempts, but unfortunately, no substantial results have been achieved so far. progress
In the current development of rose silver, either the color is not up to standard, and there is no rose color value of rose gold, or the resulting rose-colored silver alloy has poor corrosion resistance, and it will wear out within a few months in the experimental situation or fade

Abstract

The invention discloses a high-elasticity-modulus sweat-corrosion-resisting silver alloy for 22K rose silver. The high-elasticity-modulus sweat-corrosion-resisting silver alloy comprises ingredients including, by weight, 0.3%-0.5% of Be, 0.2%-0.4% of Li, 0.6%-0.8% of Ti, 0.1%-0.3% of C, 0.5%-0.6% of V, 0.2%-0.3% of Re, 2.0%-4.0% of Cu, 91.0%-92.0% of Ag and the balance Im. The rose-color silver alloy which does not exist on the market is provided, and the alloy has the excellent friction resistance. Through advanced material design, the types of silver alloys for jewelry are greatly enriched,and meanwhile, implementation and industrialization of the material can obtain rich economic gains and social benefits.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a silver alloy. Background technique [0002] One of the characteristics of gold is its softness, so it is difficult to inlay various exquisite styles, especially when inlaid with pearls, gemstones and emeralds, it is easy to be lost. Therefore, people add a small amount of silver, copper, zinc and other metals to gold to increase the strength and toughness of gold. The gold ornaments made in this way are also called K gold. K gold can be formulated into various colors according to needs, and there are various colors of K gold jewelry popular in the world. [0003] Rose gold After the sparkling gold jewelry and classic and elegant platinum jewelry, the soft and charming rose gold jewelry has gradually become the new favorite of fashion people. Pink rose gold not only symbolizes love, but also contains warm and timeless feelings, deducing a new world of precious metal jewelry. T...
