Abstract

The invention discloses a high-performance tin-phosphor bronze wire and a production method thereof. The high-performance tin-phosphor bronze wire comprises the following elements in percentage by weight: 4.3-5.0 percent of Sn, 0.06-0.12 percent of P, 0-0.03 percent of Zn, 0-0.005 percent of Fe, less than 0.0.3 percent of Si, 0-0.05 percent of Ni, 0-0.005 percent of Cd, 0-0.02 percent of total impurities, and Cu in balancing amount. The materials are smelted and drawn to cast a rod blank with the diameter of 12 mm, and then the rod blank is subjected to five-pass processing. The required optimal grain size is achieved by controlling the contents of minor elements like Fe in the tin-phosphor bronze wire and adjusting the annealing temperature, heat preservation time and processing rate in the processing process, therefore, that the material performance is uniform is ensured, and the produced tin-phosphor bronze wire has uniform performance and a smooth surface, and can meet the use requirements of customers in the high-end electronic connector assembly industry.

Description

Technical field [0001] The invention relates to a high-performance tin-phosphorus bronze wire and a production method thereof. Background technique [0002] Tin phosphor bronze has high strength, hardness, wear resistance and corrosion resistance, and is used for electronic equipment components, high-performance plug-ins, terminal blocks, etc. [0003] C51000 tin-phosphorus bronze wire products are mainly used in the high-end electronic connector industry. Due to the high performance uniformity and surface requirements of customers, it is mainly imported from abroad. Only a few domestic manufacturers have mastered the production technology of this product, but the quality of the products produced rarely can fully reach the level of imported products. [0004] The performance and surface of the tin-phosphorus bronze wire produced by the prior art cannot meet the requirements of customers in the high-end electronic connector industry. Summary of the invention [0005] In order to solv...
