Abstract

The invention discloses a corrosion-resistant, wear-resistant, and gold-free gold-imitated alloy for jewelry and decorative materials. The alloy comprises following components in percentage by weight:0.2 to 0.4 wt.% of Be, 2.0 to 2.5 wt.% of Mg, 1.0 to 1.5 wt.% of Bi, 0.6 to 0.9 wt.% of W, 0.3 to 0.5 wt.% of Ce, 2.0 to 3.0 wt.% of In, 10.0 to 15.0 wt.% of Zn, 20.0 to 25.0 wt.% of Cu, and the balance being tin. The invention provided a yellow gold-imitated alloy with an excellent performance, and the species of color alloy for jewelry and decorative materials on the market is greatly enriched.

Description

Technical field [0001] The invention relates to the technical field of alloys, in particular to an imitation gold alloy. Background technique [0002] Humans have discovered and used gold for thousands of years, which is longer than human written records. Gold has associated with humans before there are words, which has been confirmed by more and more unearthed cultural relics. Pure gold jewelry has always been popular among people. This is because pure gold has the characteristics of being pure, acid and alkali resistant, and durable, and has the greatest value, which can fully reflect the owner's qualities such as wealth, luxury, stability, and loyalty. However, when pure gold is used as a jewelry, due to its poor wear resistance, the surface is easy to be rubbed and etched when worn frequently, causing gold loss and affecting the finish of the jewelry. For this reason, by adding other elements such as Ag, Cu, Ni, Pd, Zn, etc. to pure gold to make a gold alloy, the strength a...
