Abstract

The invention discloses a method for manufacturing a copper-coated steel wire. The method includes steps of acid-washing and rustproof treatment for a steel wire; primary drawing treatment; primary heat treatment; copper electroplating; secondary drawing treatment; secondary heat treatment; and surface protection. The method has the advantages that the usage amount of copper of the copper-coated steel wire is greatly reduced under the condition of meeting the requirement on electrical conductivity, special requirements of electronic products on the mechanical performance of the copper-coated steel wire are met, and the copper-coated steel wire brings convenience for line production of the electronic products owing to an iron core; and the copper-coated steel wire can be used as a lead or a connecting wire for the electronic products, replaces a pure copper wire and is wide in application.

Description

technical field [0001] The invention relates to the field of materials, in particular to a copper-clad steel wire and a production method thereof. Background technique [0002] Copper is an excellent conductive metal and is widely used in electronic products. However, metal copper resources are scarce and expensive. Moreover, the metal copper wire is relatively soft and cannot meet the special requirements of electronic products for mechanical properties. [0003] Therefore, it is necessary to provide a copper-clad steel wire and a production method thereof to solve the above problems. Contents of the invention [0004] In order to solve this problem, the present invention discloses a production method of copper-clad steel wire, which includes the following steps: pickling and anti-embroidery treatment steps of steel wire, first drawing treatment step, first heat treatment step , a copper electroplating step, a second drawing treatment step, a second heat treatment step...
