Problems solved by technology

[0003] However, the strength of the current copper-clad steel wire is relatively weak, and it is easy to break, causing the wire to be easily damaged and affecting normal transmission; for this, the current market generally adopts a multi-layer cladding structure to solve the problem of easy breakage, such as setting an insulating layer, an alloy layer, metal layer, fiber layer, anti-oxidation layer, composite material layer, etc., but excessive coating affects the flexibility of the wire, which is not conducive to processing and use

Abstract

The invention relates to the technical field of wires, in particular to a copper-clad steel tin-plated wire and a preparation process thereof. The copper-clad steel tin-plated wire sequentially comprises a core layer, a copper layer and a tin-plated layer from inside to outside, and the thickness of the tin-plated layer is 1-3 micrometers; the preparation method of the copper-clad steel tin-platedwire comprises the following steps: A, pulling a steel wire; b, electroplating a copper layer; c, performing wire drawing and annealing treatment; d, cooling and performing air-drying treatment; ande, performing tinning treatment. The copper-clad steel tin-plated wire is novel in structure, simple in preparation process operation and easy to control, the prepared wire is high in strength, the tin-plated layer is stabilized on the basis that the high-strength copper-clad steel wire is prepared, protection on the copper layer is improved, the oxidation resistance of the wire is improved, the copper layer is not prone to oxidation discoloration or corrosion, and the service life of the wire is prolonged; and practicality is high.

Description

technical field [0001] The invention relates to the technical field of wire rods, in particular to a tinned copper-clad steel wire rod and a preparation process thereof. Background technique [0002] The surface layer of copper-clad steel wire is copper, which has good electrical conductivity, while the inner layer is high-quality carbon steel, which conducts electricity according to the skin effect principle, has excellent magnetic conductivity, and its resistance is much lower than conventional materials such as steel and galvanized steel; thus Because of its good signal transmission performance and excellent mechanical properties, it is widely used in data transmission and other fields. [0003] However, the strength of the current copper-clad steel wire is relatively weak, and it is easy to break, causing the wire to be easily damaged and affecting normal transmission; for this, the current market generally adopts a multi-layer cladding structure to solve the problem of ...
