Problems solved by technology

[0003] However, the current production cost of high-purity copper wire is high, especially the qualified rate of copper wire products with small diameter is low, which cannot meet the current market demand
In addition, the ductility of copper is worse than that of gold, and the method of doping gold is generally used to improve the ductility, which undoubtedly increases the production cost

Abstract

The invention provides a production method for manufacturing a copper wire. The production method comprises the steps that an electrolytic copper plate without layering defects is taken as a raw material, slit into copper strips, and then machined into cooper rods; then a wire rod copper wire material is manufactured, polishing is conducted, a coating is subjected to phosphorization, soaking treatment is conducted through wiredrawing protecting liquid, heat treatment is conducted, and finally, the copper wire is formed by stretching through a wire drawing machine. The copper wire has the excellent extending performance, and the product pass rate is high.

Description

technical field [0001] The invention relates to the technical field of wires, in particular to a production method for making copper wires. Background technique [0002] Copper (4N copper) with a purity of more than 99.99% belongs to chivalrous high-purity copper, while ultra-high-purity copper (5N-7N) can be broadly called high-purity copper. High-purity copper wires based on generalized high-purity copper have broad application prospects in electronic and electrical products as high-end electronic materials, such as: high-definition TV signal lines, high-quality speaker wires, special enameled wires for electric vehicle motors, vacuum Target materials for evaporation, copper strips for solar photovoltaics, etc. Compared with conventional copper, high-purity copper wire has higher purity, fewer lattice defects and impurities, which in turn endows higher electrical conductivity, better heat dissipation and better flexibility. These characteristics are The high fidelity, lo...
