Abstract

The invention discloses a 925 silver alloy with the purple appearance and brittle failure resistance, and a process thereof. The 925 silver alloy comprises the components of, by weight, 0.4-0.6% of Be, 0.8-1.2% of Li, 1.5-1.6% of Al, 0.2-0.3% of Ru, 0.6-0.8% of Sc, 1.5-1.8% of In, 92.0-93.0% of Ag and the balance copper. The 925 silver alloy provides a brand-new material with the purple appearancefor 925 silver alloys for jewelry in China, and the 925 silver alloy has the excellent characteristic of brittle failure resistance. Implementation and industrialization of the 925 silver alloy can effectively promote the demands of product renewal and industry upgrading of the jewelry industry in China, and abundant economic gains and social benefits are obtained while the industry problems aresolved.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a silver alloy. Background technique [0002] Silver is a silver-white precious metal with a charming color, and it has been used to make jewelry since early. In addition, silver also has a very wide range of uses in industry, such as making use of its conductivity to make electronic components and instruments of various precision instruments. Because silver is too soft, it is often doped with other components to form silver alloys. The silver alloy commonly used to make jewelry is sterling silver, which has been used as standard silver in the UK for 800 years, and its composition is 92.5Ag-7.5Cu. This silver alloy is often referred to as 925 silver, which generally refers to a silver product with a silver content of about 92.5wt%. [0003] 925 silver quickly became popular all over the world because it can better inlay various gemstones and produce silver products with various...
