Abstract
The invention provides 4004 aluminum alloy for braze welding. The mobility of brazing alloy can be effectively improved by the 4004 aluminum alloy; the product brazing yield is also improved. The 4004 aluminum alloy is characterized by comprising the following materials in 100 parts by weight in all: 10.2-11.2 parts of silicon (Si), not more than 0.3 parts of ferrum (Fe), not more than 0.2 parts of copper (Cu), not more than 0.05 parts of manganese (Mn), 0.5-1.0 part of magnesium (Mg), not more than 0.1 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 for soldering, be specially a kind of soldering 4004 aluminium alloys.
Background technology
A kind of aluminum alloy plate materials, it is composited by solder 4004 standard aluminum alloys, 3003 aluminium alloy cores, and this aluminum alloy plate materials and fin alloy and other accessories form whole board-like aluminium alloy heat radiator by the mode of vacuum brazing.Wherein to comprise the total mass umber be 100 parts following material to 4004 standard aluminum alloys: silicon (Si) is 9.0～10.5 parts, iron (Fe)≤0.8 part, copper (Cu)≤0.25 part, manganese (Mn)≤0.1 part, magnesium (Mg) is 1.0～2.0 parts, zinc (Zn)≤0.2 part, all the other are aluminium and unavoidable impurities element, this aluminium alloy heat radiator is in brazing process, because the illiquidity of solder 4004 standard aluminum alloys causes the joint rack of fusion easily, and plate-type heat exchanger has thousands of welding joints usually, some welding joint position is remote, because the solder fluidity deficiency is more prone to occur weld and does not fill the phenomenon that puts in place, especially more is prone to the welding leak source with the strip of paper used for sealing contact site, thereby needs repair welding even easily cause product rejection; In addition, the magnesium of 4004 standard aluminum alloys (Mg) content is higher, the existence of magnesium is arranged in the aluminium alloy, destroy the oxide film of original aluminium alloy densification easily, and the loose oxide film of formation, thereby further aggravate oxidation, thereby cause the solder surface to exist the excessive oxidation film to cause not easy-formation of welding joint, influence welding effect.
Summary of the invention
At the problems referred to above, the invention provides a kind of soldering 4004 aluminium alloys, it can effectively improve the flowability of solder aluminium alloy, improves product soldering lumber recovery.
Its technical scheme is such, it is characterized in that: it comprises the total mass umber is 100 parts following material, silicon (Si) is 10.2 parts～11.2 parts, iron (Fe)≤0.3 part, copper (Cu)≤0.2 part, manganese (Mn)≤0.05 part, magnesium (Mg) is 0.5～1.0 part, zinc (Zn)≤0.1 part, all the other are aluminium (Al) and unavoidable impurities element.
It is further characterized in that: described unavoidable impurities element summation is not more than 0.15 part, and single impurity element is not more than 0.05 part.
Soldering of the present invention 4004 aluminium alloys, the content of silicon (Si) has been improved on its basis at 4004 standard aluminum alloys, further near the Al-Si eutectic point, reduced the liquidus temperature of alloy, made to be easy to the easier fusing under same brazing temperature of this solder flow, enter the welding joint that some are difficult for filling easily, thereby improve the integral solder effect, improve welding strength, stop leak source; Soldering of the present invention has simultaneously reduced the content of magnesium (Mg) on the basis of original standard 4004 aluminium alloys with 4004 aluminium alloys, prevented the over oxidation of aluminum alloy surface, simultaneously in welding process, be unlikely to have the excessive oxidation film to exist and cause the welding joint can't moulding, thereby further improved welding effect.
