Abstract

The invention relates to a composite metal wire and a manufacturing method. The composite metal wire is formed by compositing a core body and a coating layer, and the coating layer is made of copper and particularly the copper with the weight purity ranging from 99.90% to 99.98%; the core body is an iron alloy comprising, by weight, 35% of copper, 55% of iron and 10% of aluminum; the thickness of the coating layer is from one fourth to one second the radius of the wire. 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

A kind of metal composite wire and preparation method

Technical field

The invention belongs to plain conductor field, refer to especially a kind of copper-clad iron compound wire and preparation method.

Background technology

The social benefit of using from resource and the viewpoint of saving copper resource, adopt bimetallic material also to have very real meaning as communication, electric power transfer earthed conductor.

But the mild steel that copper covered steel needs needs highly purified so processing charges is higher, its material is hard and to have high resiliency not flexible, be only suitable for for communication cable industry, in the middle of electron trade, be not suitable for using this kind of composite material to replace copper cash, so there is certain limitation.

Summary of the invention

The object of the invention is to by providing a kind of with low cost, neither too hard, nor too soft, and the high copper-cladded iron alloy composite conductor of tensile strength, solve the deficiency of existing compound wire in some application, meet the demand of all trades and professions to compound wire.

The present invention is achieved by the following technical solutions:

A metal composite wire, is composited by core body and coating layer, and wherein coating layer is copper, the copper that particularly weight purity is 99.90-99.98%; Core body is the ferroalloy of weight of copper 35%, iron weight 55% and aluminium weight 10%; Described coating thickness is the 1/4-1/2 of wire radius.

Line base through the drawing of multi-pass wire drawing die, makes copper, ferroalloy interface by metallurgical binding, become the wire of required wire diameter with wire drawing machine.

Its preparation method comprises the following steps:

Remove grease and the oxidation passivation layer on copper strips and ferroalloy line surface;

On the ferroalloy line that is 10mm-12mm at diameter by copper clad, make composite blank;

By the speed of 120m/min-150m/min, the reducing rate of 13-18% is drawn to diameter by composite blank is 3-5mm;

Adjustment drawing speed is that 1000m/min-1200m/min, reducing rate are that to be drawn to diameter be 0.5-1.2mm to 8-15%;

Adjustment drawing speed is that 1500m/min-2500m/min, reducing rate are that to be drawn to diameter be 0.08-0.5mm to 3-12%.

In drawing, in the middle of 0.08mm-1.0mm process, need do annealing in process, temperature should be controlled between 600 ℃-650 ℃.

The invention has the beneficial effects as follows:

The DC resistivity of copper-cladded iron alloy composite conductor, lower than the DC resistivity of copper covered steel wire, has guaranteed that signal transmits and is applied to the requirement of electron trade to ampacity, and loss is lower than copper covered steel wire.

Embodiment

Its preparation method comprises the following steps:
