Embodiment Construction

[0018] A metal composite wire, which is composed of a core body and a cladding layer, wherein the cladding layer is copper, especially copper with a weight purity of 99.90-99.98%; the core body is made of 35% copper by weight, 55% iron by weight and aluminum 10% iron alloy by weight; the thickness of the cladding layer is 1 / 4-1 / 2 of the wire radius.

[0019] The wire blank is drawn by a wire drawing machine through a multi-pass drawing die, so that the interface of copper and iron alloy is metallurgically combined to form a wire with a required wire diameter.

[0020] Its preparation method comprises the following steps:

[0021] Remove the grease and oxidation passivation layer on the surface of copper strip and ferroalloy wire;

[0022] Copper is coated on the iron alloy wire with a diameter of 10mm-12mm to make a composite billet;

[0023] Draw the composite blank to a diameter of 3-5mm at a speed of 120m / min-150m / min and a diameter reduction rate of 13-18%;

Abstract

The invention relates to a manufacturing method for a composite metal wire. The manufacturing method includes the following steps that the composite metal wire is formed by compositing a core body and a coating layer, and grease and oxidization and passivation layers on the surfaces of copper strips and iron alloy wires are removed; the iron alloy wires are coated with copper to manufacture a composite blank; the wire blank is drawn through a wire-drawing die in a multi-pass mode by a drawbench, the wire with the needed diameter is formed through metallurgical bonding of the copper and iron alloy interfaces. The direct-current resistivity of the composite wire made of the copper-coated iron alloy is lower than that of a copper-coated steel wire, signal transmission is ensured, the requirement for the carrying capacity when the composite metal wire is applied to the electron industry is met, and the loss of the composite metal wire is smaller than that of the copper-coated steel wire.

Description

technical field [0001] The invention belongs to the field of metal wires, in particular to a method for preparing copper-clad iron composite wires. Background technique [0002] From the point of view of the social benefits of resource use and the saving of copper resources, it is also of great practical significance to use bimetallic materials as ground conductors for communication and power transmission. [0003] However, the low-carbon steel required by copper-clad steel needs to be highly purified, so the processing cost is high. Its material is hard and has high elasticity and is not easy to bend. It is only suitable for the communication cable industry. It is not suitable to use this composite material instead of copper in the electronics industry. line, so there are certain limitations. Contents of the invention [0004] The purpose of the present invention is to solve the deficiencies of existing composite wires in certain application fields by providing a copper-...
