Description

A kind of two high-conductivity energy silver-bearing copper recombination line

Technical field

The utility model relates to a kind of alloy silver-copper wire, is specifically related to a kind of two high-conductivity energy silver-bearing copper recombination line.

Background technology

Two high-conductivity energy silver-bearing copper composite wire is the structure function material that a class has excellent combination physical property and mechanical property, has both had high intensity and good plasticity, and has had again good conduction, thermal conductivity.Have wide practical use in fields such as hyundai electronics information technology, communications and transportation, Aero-Space, national defence.Two high-conductivity energy silver-bearing copper composite wire is also that preparation holds differently stressed various conductions, the important materials of conductive structure part, as conductive seat, the electrode of all kinds of large-scale resistance welder; Large volume automobile turbine generator rotor slot wedge, retaining ring, collector ring, armature; All kinds of electric resistance welding, as butt welding, spot welding, seam weldering, the electrode of roll welding, conducting rod, weldering arm, welding torch ignition tip, gas cutting machine nozzle; The lead frame of integrated circuit, the contact wire of electrified high speed electrical equipment train, horizontal caster crystallizer liner, high_voltage isolation conducting rod etc.And singly to conduct electricity or heat conductivility silver-bearing copper composite wire is difficult to take into account, the high-tech such as space flight, aviation, electronics, communication, traffic, electromechanics can not be met comprehensively and develop requirement to its combination property rapidly.Along with the fast development of hyundai electronics communication, require that the performance of various electric-conductivity heat-conductivity high copper alloy wire is more and more higher, namely high conductivity and high thermal conductivity have both, if integrated circuit is towards extensive and ultra-large development, while the high-fidelity wire that sophisticated digital communication apparatus (Signal transmissions), smart appliances use, super-high magnetic field water-cooled copper wire, bullet train, the coil windings of micro machine, Aero-Space and defence equipment copper alloy wire require that its conductance remains on 70% ~ 80%IACS, tensile strength reaches 350 ~ 600MPa.

Developed countries has carried out a large amount of research and development to two high-conductivity energy silver-bearing copper composite wire technology of preparing, the developed country such as the U.S., Japan has international most advanced level in two high-conductivity energy silver-bearing copper composite wire Study on Preparation Technology field, captures the two high-conductivity copper alloy composite wire market of major part.And the electric conductivity that domestic employing separates and heat conductivility, product automation level is low, and product quality cannot ensure its pair of high-conductivity energy, and power consumption is large, unstable, the shortcomings such as yield rate is low.

Application number is 201120485674.7, the applying date is on November 29th, 2011, Authorization Notice No. is that the utility model of CN202332324U discloses a kind of painting silver dollar copper cash, comprise Copper substrate, fine silver layer, described fine silver layer is located at Copper substrate on the surface, sliver diffusion layer is provided with between described fine silver layer and Copper substrate, mainly solve silver, the transition problem that copper combines, product quality is guaranteed, but the sliver diffusion layer of this patent can not ensure the uniformity of outside fine silver layer, say from cost, silver meeting many, electric conductivity and heat conductivility may decline.

Utility model content

The utility model, in order to improve two high-conductivity energy of yellow gold, provides a kind of two high-conductivity energy silver-bearing copper recombination line.

The purpose of this utility model is achieved through the following technical solutions:

A kind of two high-conductivity energy silver-bearing copper recombination line, comprises Copper substrate and silver-bearing copper composite bed, arranges silver layer, arrange protective layer outside described silver layer outside described silver-bearing copper composite bed.

Described protective layer is anti-oxidation, etch-proof protective layer.

Described protective layer is nickel protection layer.

The beneficial effects of the utility model are:

In the application, silver-bearing copper composite bed, is pre-plating layer usually, mainly in order to ensure the even performance of outside fine silver layer; Silver-bearing copper composite bed outside is fine silver layer, and be also coating, most external is high-grade anti-oxidation insulating materials, improves two high-conductivity energy of silver-bearing copper recombination line, pre-plating layer and coating is effectively combined, guarantees the uniformity of silver thickness, save raw material.

Fig. 1 is the cross-sectional structural representation of the utility model.

Fig. 2 is the utility model partial cutaway structural representation.

Detailed description of the invention

As depicted in figs. 1 and 2, a kind of two high-conductivity energy silver-bearing copper recombination line, comprises Copper substrate 1 and silver-bearing copper composite bed 2, arranges silver layer 3 outside described silver-bearing copper composite bed 2, arrange protective layer 4 outside described silver layer 3.Described protective layer 4 is anti-oxidation, etch-proof protective layer.Described protective layer is nickel protection layer.

The utility model conductance is high, heat conductivility is strong, obdurability is good, can replace traditional list conduction, single heat conductivility silver-bearing copper composite wire, meets the high-tech such as space flight, aviation, electronics, communication, traffic, electromechanics comprehensively and develops requirement to silver-bearing copper composite wire combination property rapidly.
