Abstract
The invention provides a 4343 aluminum alloy for brazing. The solder 4045 aluminum alloy can effectively reduce a corrosion potential of a solder aluminum alloy, and prolong a service life of a radiator. The 4343 aluminum alloy is characterized by comprising the following components at total mass fraction 100%: 6.8 to 8.2 parts of silicon (Si), not greater than 0.8 parts of ferrum (Fe), not greater than 0.25 parts of copper (Cu), not greater than 0.1 parts of manganese (Mn), not greater than 0.05 parts of magnesium (Mg), 0.8 to 1.2 parts of zinc (Zn), and the balance of aluminum (Al) and inevitable impurity elements.
Description
Technical field
The present invention relates to the aluminum alloy materials technical field, especially relate to the solder aluminium alloy that is used for soldering, be specially a kind of soldering and use 4343 aluminium alloys.
Background technology
A kind of aluminium alloy heat radiator pipe, it is made through the form that high-frequency welding perhaps overlaps by the composite band that solder 4343 standard aluminum alloys, 3003 aluminium alloy cores and water side protective layer 7072 aluminium alloy compound form, and this aluminium alloy heat radiator water pipe and aluminum alloy fin material are welded into integral body through the form of soldering; Wherein to comprise the gross mass umber be 100 parts following material to 4343 standard aluminum alloys: silicon (Si) is 6.8%～8.2%; Iron (Fe)≤0.8 part, copper (Cu)≤0.25 part, manganese (Mn)≤0.1 part; Magnesium (Mg)≤0.05 part; Zinc (Zn)≤0.2 part, all the other are aluminium and unavoidable impurities element, this aluminium alloy heat radiator pipe is in use because higher as the corrosion potential of 4343 aluminium alloys of solder; Cause radiator tube to be prone to the spot corrosion leakage, radiator is low service life.
Summary of the invention
To the problems referred to above, the invention provides a kind of soldering and use 4343 aluminium alloys, it can effectively reduce the corrosion potential of solder aluminium alloy, prolongs the service life of radiator.
Its technical scheme is such, it is characterized in that: it comprises the gross mass umber is 100 parts following material, and silicon (Si) is 6.8 parts～8.2 parts; Iron (Fe)≤0.8 part; Copper (Cu)≤0.25 part, manganese (Mn)≤0.1 part, magnesium (Mg)≤0.05 part; Zinc (Zn) is 0.8 part～1.2 parts, and all the other are aluminium (Al) and unavoidable impurities element.
It is further characterized in that: said unavoidable impurities element summation is not more than 0.15 part; Single impurity element is not more than 0.05 part in the said unavoidable impurities element.
4343 aluminium alloys are used in soldering of the present invention; It has increased the content of the zinc (Zn) that can play the effect of effective reduction alloy corrosion current potential on the basis of 4343 standard aluminum alloys; Thereby under the situation that does not influence this aluminum alloy materials operating characteristic, reduced the corrosion potential of alloy; It has played the effect of transition zone as solder between fin and radiator tube core, the fin that corrosion potential is minimum in the radiator tube use at first corrodes, and in the time of the fin corrosion electronics is transferred to brazing filler metal alloy of the present invention; And aluminum alloy materials of the present invention is because its corrosion potential is low than the corrosion potential of 3003 aluminium alloy core materials; Can be transferred to the core surface prior to the core corrosion and with electronics, make fin, brazing filler metal alloy of the present invention, core form a corrosion gradient, forms of corrosion changes whole face erosions into by the part spot corrosion; Slowed down the time of corrosion leakage, thus the service life of improving radiator greatly.
