Abstract
The invention discloses a tinned copper clad aluminum magnesium wire which comprises aluminum magnesium core wires and a copper layer. The copper layer is coated on the aluminum magnesium core wires, a tin layer is arranged on the outer side of the copper layer in a plating mode, and a zinc nickel mixing layer is arranged between the copper layer and the tin layer. Through the above method, the plating tin aluminum magnesium wire is simple in structure, good in conductivity performance and mechanical performance, good in shielding effect, low in cost, and capable of saving copper resources largely. Meanwhile, the plating tin aluminum magnesium wire can further prevent copper ions from spreading towards the tin layer to result in the phenomenon of oxidization production, and good usage performance of the wire after long-time storage is ensured.
Description
Technical field
The present invention relates to the wire rod field, particularly relate to a kind of zinc-plated magnalium wire rod.
Background technology
At present, it is all to adopt fine copper as wire that many places are arranged on a lot of expensive goods or visual plant, and copper cash has good electric conductivity and good mechanical mechanics property, therefore is widely used already.But the copper wire quality is large, and resource scarcity is expensive, thereby use cost is higher, and for copper cash, the aluminum steel quality is light, and electric conductivity is better, but mechanical mechanics property is relatively poor.In addition, the tin-plated pure copper line that adopts at present because of its Heavy Weight, although this metal composite wire has good electric conductivity, signal transmission performance and mechanical property, because its inner core all adopts fine copper, therefore, makes production cost and use cost very high.
Summary of the invention
The technical problem that the present invention mainly solves is to provide and a kind ofly can satisfies electric conductivity and mechanical mechanics property, and obviously lowers the zinc-plated magnalium wire rod of the cost of raw material.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of tin-coated copper plated aluminium magnesium wire rod is provided, comprises: magnalium heart yearn, copper layer are coated with the copper layer on described magnalium heart yearn, the outside plating of described copper layer is provided with the tin layer, is provided with the zinc-nickel mixed layer between described copper layer and described tin layer.
In a preferred embodiment of the present invention, the sectional area ratio scope of described copper layer and magnalium heart yearn is 2: 20-1: 10.
In a preferred embodiment of the present invention, described zinc-nickel mixed layer comprises zinc, nickel, and the mixed proportion between described zinc and nickel is 1: 1.
In a preferred embodiment of the present invention, described zinc-nickel mixed layer is identical with described copper layer thickness.
The invention has the beneficial effects as follows: the present invention is simple in structure, and electric conductivity, mechanical mechanics property are good, and shield effectiveness is good, and cost is low, has greatly saved the copper resource; Can also prevent that simultaneously copper ion to the diffusion of tin layer, producing the phenomenon of oxidation, guarantee good serviceability after the wire rod long preservation.
Description of drawings
Fig. 1 is the structural representation of tin-coated copper plated aluminium magnesium wire rod one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, magnalium heart yearn, 2, the copper layer, 3, the tin layer, 4, the zinc-nickel mixed layer.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the present invention comprises:
A kind of tin-coated copper plated aluminium magnesium wire rod comprises: magnalium heart yearn 1, copper layer 2, be coated with copper layer 2 on described magnalium heart yearn 1, and described copper layer 2 outside plating are provided with tin layer 3, and described copper layer 2 is 2 with the sectional area ratio scope of magnalium heart yearn 1: 20-1: 10.
Be provided with zinc-nickel mixed layer 4 between described copper layer 2 and described tin layer 3.Described zinc-nickel mixed layer 4 comprises zinc, nickel, and the mixed proportion between described zinc and nickel is 1: 1.Described zinc-nickel mixed layer 4 is identical with described copper layer 2 thickness.Can effectively prevent the 2 copper ion oxidation of copper layer, avoid the serviceability variation of wire rod after long preservation.
Tin-coated copper plated aluminium magnesium wire rod of the present invention is a kind of economy, good, safety, and with the tin-coated copper plated aluminium magnesium wire rod of good function of shielding.
During making, first with coated copper layer 2 after 1 alkali cleaning of magnalium heart yearn, through welding and stretching, make copper layer 2 and magnalium heart yearn 1 carry out metallurgical binding, form aluminium in copper magnesium heart yearn 1, then aluminium in copper magnesium heart yearn 1 coats and is provided with zinc-nickel mixed layer 4, then is adopting zinc-tin technique at zinc-nickel mixed layer 4 outsides plating one deck tin layers 3, thereby forms a kind of tin-coated copper-clad aluminum-magnesium alloy shielding braided line conductor that has more good cost performance.
The present invention is simple in structure, and electric conductivity, mechanical mechanics property are good, and shield effectiveness is good, and cost is low, has greatly saved the copper resource; Can also prevent that simultaneously copper ion to 3 diffusion of tin layer, producing the phenomenon of oxidation, guarantee good serviceability after the wire rod long preservation.
The above is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
