The utility model provides a weldable aluminum strip, the continuous electroplating is adopted, the electroplating efficiency can be improved, the environment pollution degree is reduced, and the cost of using tin as the weldable plating layer is lower than the cost of using nickel as the weldable plating layer.
Description
Technical field
The utility model relates to a kind of zinc-plated aluminum alloy strip, especially a kind of radiator element zinc-plated aluminum alloy strip of weldability.
Background technology
In the fast development of computer chip, LED lamp, its crucial heat dissipation problem is following at present.At present the integrated level of computer chip is more and more higher, and it requires also more and more higher to heat radiation, and air-cooled radiator mainly contains three kinds of full aluminium, full copper and copper aluminium combined types at present.It is high that the thermal conductivity ratio aluminium of copper is wanted, though copper is faster than aluminium on heat absorption speed, the speed of aluminium is just in time faster on heat release speed, and copper aluminium combined type has been taken into account both advantages.The welding property of aluminium is poor, and the utility model has solved this problem.But adopt welding aluminum sheets, can directly aluminum bronze be welded together, need not other more operations.Aluminium is as the heat sink material of LED lamp, and the welding of adopting aluminium also is a key issue, but adopts welding aluminum sheets, improves novel process, and the LED light temperature is descended 4.5 ℃, thereby has increased the stability and the life-span of LED lamp.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the low weldability of a kind of cost zinc-plated aluminum alloy strip.
According to the technical scheme that the utility model provides, the zinc-plated aluminum alloy strip of a kind of weldability comprises base material, and feature is: at the upper and lower electroplating surface flash nickel dam of described base material, electroplate one deck tin coating on the outside surface of flash nickel dam.
The thickness of described base material is 0.1～1 millimeter, and the width of described base material is 300～1200 millimeters.
The thickness of described tin coating is 0.1～10 millimeter.
The thickness of described flash nickel dam is 0.01 ~ 0.5 micron.
The utility model provides a kind of weldability aluminium strip, adopts continuous electroplating can improve its electroplating efficiency, reduces the environmental pollution degree; Comparatively cheap with respect to the nickel cost with tin as solderable coating.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in the figure: the zinc-plated aluminum alloy strip of weldability comprises base material 1, flash nickel dam 2, tin coating 3 etc.
The utility model base material 1 is selected L5-1 aluminium alloy plate (band) for use, and described base material 1 is made by oil removing, pickling, after soaking zinc, flash nickel, eleetrotinplate; At the upper and lower electroplating surface flash nickel dam 2 of base material 1, on the outside surface of flash nickel dam 2, electroplate tin coating 3;
Described base material 1 thickness is 0.1～1 millimeter, and the width of described base material 1 is 300～1200 millimeters; The thickness of described tin coating 3 is 0.1～10 millimeter; The thickness of described flash nickel dam 2 is 0.01 ~ 0.5 micron.
Described flash nickel dam 2 and tin coating 3 obtain by following operation: soak zinc alloy → nitric acid base material uncoiling → oil removing → washing → alkali lye etching → washing → nitric acid cleaning → washing → first time and move back and soak zinc alloy → flash nickel → eleetrotinplate → air-dry → rolling zinc → second time.Flash nickel dam 2 applies cathodic current by base material 1 and obtains in the nickeliferous ion solution of tart, thickness is 0.1 micron; Tin coating 3 is handled the back by the substrate passed former procedures and apply the cathodic current acquisition in the stanniferous ion solution, and thickness is 1 micron thickness.After through hot blast drying behind the eleetrotinplate, batch rolling.The weldability and the heat dispersion of the zinc-plated aluminum alloy strip of weldability described in the utility model are splendid, can be used as LED lamp, the manufacturing of computer chip scatterer.
