Abstract
Disclosed is a high strength and high conductivity composite copper wire. An oxygen-free copper layer is concentrically coated on the surface of a copper alloy core wire, the copper alloy core wire of the composite copper wire is combined with the oxygen-free copper layer by means of electroplating, and the volume of the oxygen-free copper layer of the composite copper wire is 15%-20% of that of the copper alloy core wire. The composite copper wire has the advantages of good conductivity, superior signal transmission performance, good mechanical property and low cost.
Description
Technical field
The utility model relates to a kind of high strength, the compound copper cash of high conductivity, belongs to technical field of electric wires and cables.
Background technology
Economic rapidly flourishing today, the demand of copper increases severely day by day, particularly concerning the electric wire manufacturing industry, provides high-quality copper effectively to ensure the people's lives and property safety.Conductor, screen, armour to electric wire; Not only require excellent, the most of occasion of electric conductivity of metal wire rod to require metal wire rod to have certain mechanical strength; And these performance requirements are that general pure copper wire institute is unappeasable, and the cost of pure copper wire is higher.Therefore, a kind of high strength that waits in expectation on the market, the compound copper cash of high conductivity have excellent conductivity, signal transmission performance and mechanical property, and cost are low, can replace pure copper wire to be used for wire products.
The utility model content
The purpose of the utility model is to provide a kind of high strength, the compound copper cash of high conductivity, and this copper cash has excellent conductivity, signal transmission performance and mechanical property, and cost is low; Can overcome defectives such as existing pure copper wire mechanical strength is low, cost height.
The technical scheme of the utility model is: a kind of high strength, the compound copper cash of high conductivity coat one deck oxygen-free copper layer with one heart on copper alloy heart yearn surface.Described compound copper cash is that copper alloy heart yearn and oxygen-free copper layer adopt the compound copper cash of electroplating combination.
The oxygen-free copper layer of described compound copper cash accounts for 15～20% of copper alloy wire core volume ratio.
The beneficial effect of the utility model is: it is that fine copper has excellent conductivity, signal transmission performance that high strength, the compound copper cash of high conductivity have used the oxygen-free copper layer; Simultaneously have the mechanical property that the copper alloy heart yearn is had again, and cost is low.Replaced original pure copper wire, the manufacturing cost of cable is reduced greatly, and, be a kind of high strength, the compound copper cash of high conductivity, each item index all is higher than products standards.
Description of drawings
Fig. 1 is a kind of high strength of the utility model, the schematic cross-section of the compound copper cash of high conductivity (some amplification of superficial layer is clear for representing among the figure).
Among the figure, 1-copper alloy heart yearn, 2-fine copper superficial layer.
Embodiment
Be elaborated below in conjunction with accompanying drawing and specific embodiment, Fig. 1 is a kind of high strength of the utility model, the schematic cross-section of the compound copper cash of high conductivity.Among the figure, 1-copper alloy heart yearn, 2-fine copper superficial layer.
Conductivity principle according to copper conductor; Copper line surface is mainly used in conduction and signal transmission performance, and the copper core is main with mechanical properties such as its intensity of performance, therefore; The compound copper cash of the utility model; Coating one deck oxygen-free copper layer 2 with one heart on copper alloy heart yearn 1 surface, is that copper alloy heart yearn and oxygen-free copper layer adopt the compound copper cash of electroplating combination; Among the figure, 1-copper alloy heart yearn, 2-fine copper superficial layer; Both utilize excellent conduction and the signal transmission performance of fine copper, utilized mechanical properties such as copper alloy wire core body intensity again, simultaneously; With regard to cost, the cost of copper alloy core 1 body is more much lower than the cost of fine copper 2, so the utility model use coats one deck oxygen-free copper layer 2 with one heart on copper alloy core 1 line surface; The compound copper cash of processing is a kind of high strength, the compound copper cash of high conductivity.The oxygen-free copper layer 2 of described compound copper cash accounts for 15～20% of copper alloy core 1 volume ratio.Cost is more much lower than fine copper.
Embodiment 1
A kind of high strength, the compound copper cash of high conductivity coat one deck oxygen-free copper layer 2 with one heart on copper alloy heart yearn 1 surface; The oxygen-free copper layer of described compound copper cash accounts for 15～20% of copper alloy wire core volume ratio; The copper alloy heart yearn 1 of described compound copper cash and oxygen-free copper layer 2 adopt to electroplate and combine;
The composition of the copper alloy heart yearn of compound copper cash is Mg:0.5%, Ni:0.6%, Si:0.2%, Zr:0.1～%, remains to be Cu;
The composition of oxygen-free copper layer is P:0.0002%, Bi:0.00005%, Sb:0.0002%, As:0.0003%, Fe:0.0005%, Ni:0.0005%, Pb:0.0003%, Sn:0.0001%, S:0.0010%, Zn:0.00006%, O:0.0001%, remains to be Cu.
The design of the utility model to those skilled in the art, can be derived a plurality of similar technical schemes, and still, each technical scheme is all among the claim protection range of the utility model.
