Problems solved by technology

Therefore, the traditionally used pure copper wire does not have much advantage in high-frequency signal transmission, but it consumes a lot of copper resources in vain, which increases the cost of manufacturers day by day.

Embodiment Construction

[0013] The specific implementation manner of the present invention will be described in further detail below through the description of the best embodiment with reference to the accompanying drawings.

[0014] as attached figure 1 As shown, the copper-clad aluminum alloy composite wire is composed of an outer pure copper layer 1 and an inner aluminum alloy core wire 2 .

[0015] The cleaned and air-dried pure copper strip and the aluminum alloy core wire enter the composite unit synchronously. The pure copper strip passes through six sets of vertical and horizontal alternately arranged molds, and gradually forms a round tube to wrap around the aluminum alloy core wire. Then, the on-line argon Arc welding uses the protection of inert gas argon to weld the tubular pure copper strip longitudinally to form a fully enclosed round tube and wrap it around the aluminum alloy core wire to form a copper-clad aluminum alloy composite wire billet. Among them, there is a gap between the p...

Abstract

The invention discloses a copper-clad aluminum alloy compound wire. The copper-clad aluminum alloy compound wire is characterized by being manufactured through the steps of feeding cleaned and air-dried pure copper strips and aluminum alloy core wires into a compound machine unit and performing online argon arc welding, online cold drawing and thermal treatment. The copper-clad aluminum alloy compound wire is also characterized in that the thickness of outer pure copper is 0.1-0.3 mm, and the diameter of core aluminum alloy is phi 0.5-3 mm. The copper-clad aluminum alloy compound wire can be widely applied to cable shielding screen wires, coaxial cable signal transmission wires and the like and achieves the important aims of saving copper resources, reducing the production cost and avoiding environmental pollution.

Description

technical field [0001] The invention relates to the technical field of low-cost and high-performance metal composite materials, in particular to a copper-clad aluminum alloy composite wire. Background technique [0002] In recent years, due to the increasing shortage of copper resources worldwide, the price of electrolytic copper futures continues to rise, [0003] Domestic industries that use copper as the main raw material have been greatly impacted. The entire industry is in urgent need of a raw material that can not only ensure product performance, but also reduce production costs to replace pure copper. [0004] According to the "skin effect" of the current, at high frequencies above 5MHz, its conductivity mainly depends on the outer metal, especially in the fields of video information, data transmission and signal shielding, basically completely depends on the outer metal of the wire. Therefore, the traditionally used pure copper wire does not have too many advantages...
