Problems solved by technology

It is mainly to solve the difficult-to-cut performance of copper alloy, so as to obtain an easy-to-cut copper alloy. Although the copper alloy has certain anti-discoloration performance in artificial sweat or salt spray atmosphere, but because it is a white copper alloy , on the one hand, it cannot meet the requirements of gold-like copper alloy; on the other hand, it cannot reflect its anti-tarnish performance well.

Abstract

The invention relates to argentiferous gold-simulating copper alloy and a preparation method thereof and belongs to the technical field of alloy materials. The argentiferous gold-simulating copper alloy aims to solve the technical problems of poor color change resistance and gold-simulating effect of copper alloy in the prior art, and mainly comprises, by weight, 1%-20% of Ag, 0.5%-40% of Zn, not more than 1% of Si, not more than 1% of RE, 0.4-5.0% of color matching agents and the balance Cu. The preparation method includes: melting the raw materials at the temperature of 1200-1300 DEG C, performing annealing treatment at the temperature of 500-600 DEG C, forging and performing hot rolling so that the argentiferous gold-simulating copper alloy is obtained. The argentiferous gold-simulating copper alloy is high in color change resistance and good in gold-simulating effect and has the advantages of capability of achieving apparent color and luster of 14K-18K gold, simple technical process, good processability and easiness in processing.

Description

technical field [0001] The invention relates to an imitation gold-copper alloy, in particular to a silver-containing imitation gold-copper alloy and a preparation method thereof, belonging to the technical field of alloy materials. Background technique [0002] Gold has a beautiful golden yellow color, good chemical stability, and has the function of preserving value. Therefore, it has long been the material of choice for products such as jewelry, art sculptures, religious supplies, and prizes. However, in recent years, with the change of people's consumption concept, more attention is paid to the novelty of styles for jewelry, art sculptures, religious articles, prizes, etc., and the requirements for the value preservation function are weakened. Therefore, cheap and attractive imitation gold alloy products obtain people's general attention. [0003] At present, domestic imitation gold products are mainly imitation gold electroplating products and copper-based imitation gol...
