Decorative copper alloy refers to the alloy in which copper and other metals such as zinc, aluminum and nickel are mixed and melted in a certain proportion. This material not only has the beautiful color of copper, but also has the advantages of other metals, such as zinc can enhance the hardness and toughness of the material, aluminum can improve the corrosion resistance and wear resistance of the material, and nickel can increase the ductility and strength of the material. Therefore, the production technology and material selection of jewelry copper alloy are very important to product quality.

In daily life, copper alloy jewelry is widely used in jewelry, watches and clocks, home decoration and other fields. Its use not only increases the aesthetics of the product, but also has high stability and durability. Compared with pure copper jewelry, the copper alloy of jewelry has higher hardness and is not easy to deform and be oxidized and corroded. Coupled with the low production cost, it is recognized by more and more consumers.

In traditional handmade jewelry, copper alloy jewelry is also widely used. Crafts make the copper alloy jewelry more distinctive and scientific, and can also be customized according to customer needs. For some people who like hand-making, the processing of jewelry copper alloy is relatively easy, and it can be a good creative material combined with various modeling designs and manufacturing processes. At the same time, it also promoted the inheritance and development of handicrafts.
