Description
Technical field
The present invention relates to a kind of solder wire material, relate in particular to a kind of flux-cored wire that copper and aluminium welding connects that is used for.
Background technology
The heat exchanger of traditional automobile, air-conditioning and refrigeration industry all is as main material with copper.Because the copper fusing point is high, be convenient to welding, secondly copper has good heat conduction speed, tensile strength, anti-explosion power and anti-leakage ability, thereby finds broad application.Nowadays, along with the resource shortage of copper, the price of copper skyrockets rapidly, makes that automobile, air-conditioning and refrigeration industry manufacturer cost pressure are increasing.This also makes industrial quarters also begin to seek the substitute of copper.Along with development of science and technology, now, a kind of novel the copper pipe substitute--copper aluminum composite pipes comes out, and has obtained the favor of many manufacturers.The heat exchange effect of copper aluminum composite pipes is superior to fine copper tubing; It has advantages of higher tensile strength (110MPa-130MPa), anticracking pressure (180MPa) preferably, and percentage elongation is greater than 35%; Can satisfy the standard of air-conditioning and refrigeration industry fully; And price is far below pure copper tube, and weight has also reduced by 30%, is the optimum substitute of copper pipe.
The welding of copper and copper is easy to realize that the oxide-film of copper also is easier to remove.The welding of copper aluminum composite pipes usually can run into the welding of copper aluminium, often meets many Welding Problems in the welding in this field in recent years.Primary problem is the chemical property of aluminium, and the metal surface has the Al of the fine and close infusibility of one deck under the aluminium normal temperature
2O
3Oxide layer, during welding as can not in time removing this oxide layer, just postwelding can produce defectives such as pore, elephant skin, fracture, tension intensity be low.Nowadays commercially available KF-AlF
3Brazing flux and CsF-AlF
3Brazing flux can solve the ability of removing oxide layer and reaching welding.
No matter be air-conditioning, refrigeration industry or heat exchanger, very high to the requirement after the welding.The environment that joint faced after the welding is also abominable relatively, and high temperature, low temperature, high pressure and ageing-resistant ability are undoubtedly the major test of butt joint.But pure Zn-Al flux-cored wire cooperates the requirement after this brazing flux can not satisfy welding, mainly is tension intensity, air-tightness and the ageing resistace of postwelding, and the scolder fusing point is on the low side, and wetability and penetrating power are all relatively poor relatively.In recent years, Germany, the U.S., Korea S have developed some novel Zn-Al flux-cored wires in succession, and get into Chinese market, but do not receive user's popular welcome, and reason wherein except costing an arm and a leg, mainly is technical many deficiencies that still have on the one hand.Wherein, it is on the low side that major defect is exactly (1) solder fusing point, generally has only 380-420 ℃; (2) wetability and permeability are relatively poor.
To above-mentioned deficiency, discover, in Zn-Al alloy, add metals such as Ag, Ce, Cu, Si, La, not only can significantly improve Zn-Al alloy fusing point, but also can significantly improve Zn-Al alloy in high-strength aluminum alloy wetting of surfaces property, permeability.Can improve the mechanical property at Zn-Al alloy pricker (weldering) peak in addition.Particularly in the welding of albronze, the wetability on albronze, permeability are that the flux-cored wire of main component has significant improvement with the Zn-Al alloy.Therefore, realization of the present invention can be used for the welding of copper aluminium, thereby satisfies China's household electric appliances, refrigeration industry and other relevant industries new products, the new construction needs to solder technology.
Summary of the invention
To the deficiency of prior art, the object of the present invention is to provide a kind of flux-cored wire that copper and aluminium welding connects that is used for, it is good to have wetability and penetrating power, the welding back characteristics that air-tightness is good, tension intensity is high.
Technical scheme of the present invention is: a kind ofly be used for the flux-cored wire that copper and aluminium welding connects; Chemical composition and percentage by weight are in the solder wire material: Ce 0%-1.0%, La 0%-1.0%, Cu 0%-15%, Ag 0%-10%, Si 0%-12%, Al 1-15%, all the other are Zn and other inevitable impurity.
In preferred embodiment of the present invention; Chemical composition and preferable percentage by weight are in the solder wire material: Ce0%-0.01%, La 0%-0.01%, Cu 5%-10%, Ag 0%-0.1%, Si 3%-6%, Al 8-12%, all the other are Zn and other inevitable impurity.
In preferred embodiment of the present invention, chemical composition and optimum weight percentage are in the solder wire material: Ce 0.008%, La 0.005%, Cu 7%, Ag 0.05%, Si 4%, Al 9.3%, all the other are Zn and other inevitable impurity.
Of the present inventionly be used for flux-cored wire that copper and aluminium welding connects in existing Zn-Al alloy structure; Add alloying metals such as Ce, La, Cu, Ag, Si; Thereby make albronze air-tightness, tension intensity, wetability and penetrating power after welding, the decay resistance combination property is promoted comprehensively.
The adding of Al can improve the intensity that copper and aluminium welding connects the back joint, can keep good plasticity and toughness again, and is too high but the content of Al should not add, and because of being controlled at 1-15%, otherwise can influence melting temperature.
The adding of Cu can improve the intensity that copper and aluminium welding connects the back joint, and the spreadability on aluminium is improved but the adding of copper can make welding wire, but the spreadability variation on copper, so the content of copper should be controlled at 0.1%-15%.
Can better cooperate brazing flux thereby the adding of Trace Ag, Si can be heightened the fusing point of solder wire material, have heat resistance and ageing resistace reliably after the welding.
Crystal grain that can the refinement solder wire material in the adding microcosmic of Ce, La has reduced the surface tension of scolder, has improved the wetability and the penetrating power of scolder during welding.Postwelding has reduced the recrystallization of alloy, thereby the potential difference that has reduced between metal and the metal has increased ageing resistace.
The beneficial effect that is used for the flux-cored wire that copper and aluminium welding connects of the present invention is: the present invention is through appropriate design of welding wire chemical composition; Make welding wire have wetability and penetrating power preferably; Performance is drawn in good pulling out; Good fluidity, weld strength are high, good, the free from corrosion characteristics of postwelding of postwelding air-tightness, during the copper and aluminium welding that is widely used in heat exchanger in air-conditioning, refrigerator, automobile and the refrigeration industry or radiator connects.
