Abstract
The invention discloses a method for preparing heat exchange braze welding coating layer alloy plate, which is characterized in that: the weight percentage of the main chemical elements of the braze welding coating layer alloy is as follows: 7.0 percent to 12 percent of silicon (Si), 0.8 percent of ferric (Fe), 0.25 percent of Copper (Cu), 0.1 percent of manganese (Mn), 0.05 percent to 0.3 percent of magnesium (Mg), 0.2 percent of zinc (Zn) and the remaining aluminum (Al). The plank is prepared by adopting melting casting, hot rolling and cold rolling, and is changed into braze welding coating layer alloy plate by tempering treatment and commercial braze welding heat treatment. The tensile strength, yielding strength and extending rate of the alloy plate are more advantageous. The invention has good application prospect in heat exchanging situations.
Description
Technical field
The present invention relates to the preparation method of a kind of scatterer or condenser heat-exchange brazing coating alloy plate.
Background technology
In the prior art, extensively applied to scatterer, the condenser in fields such as automobile, electronics, chemical industry, building, aerospace, all make with copper material and aluminium, in the competition of aluminium and copper material scatterer, because of the price of aluminium a little less than copper material, therefore aluminium radiator holds advantage slightly, particularly automobile develops to directions such as miniaturization, lightweight, high-performance, low cost, durabilitys with scatterer, and the copper aluminium radiator is not only heavy, consumptive material, and defective such as cost height, can not satisfy the needs of automotive industry and related industries development.
Summary of the invention
In view of the existing technical problem of known technology, purpose of the present invention aims to provide a kind of high strength, high-performance, in light weight, scatterer aluminum alloy plate materials that cost is low.
The present invention has adopted following preparation method, this brazing coating alloy comprises N4343 and N4147 alloy, the weight percent of its chemical element is silicon (Si) 7.0～12%, iron (Fe) 0.8%, copper (Cu) 0.25%, manganese (Mn) 0.1%, magnesium (Mg) 0.05～0.3%, zinc (Zn) 0.2%, aluminium (Al) surplus, adopt melting and casting+hot rolling+cold-rolling process to be prepared into sheet material, sheet material promptly becomes the brazing coating aluminium alloy plate through temper and commercial soldering thermal treatment.
This aluminum alloy plate materials is compared with known technology, the fin of this brazing coating alloy plate and brazing core-layer aluminum alloy plate is used, when soldering, need not to apply again braze, make aluminium alloy heat radiator have good soldering function and machining functions, thereby simplified the manufacturing process of scatterer, condenser, reduced cost, improved intensity, alleviated weight, more made automobile reach light-weighted purpose.
Embodiment
Enumerate two representative embodiment below, the chemical element weight percent of its N4147 brazing coating alloy plate is a silicon (Si) 12%, iron (Fe) 0.8%, copper (Cu) 0.25%, manganese (Mn) 0.1%, magnesium (Mg) 0.3%, zinc (Zn) 0.2%, aluminium (Al) surplus, the chemical element weight percent of its N4343 brazing coating alloy plate is a silicon (Si) 7.0%, iron (Fe) 0.8%, copper (Cu) 0.25%, manganese (Mn) 0.1%, magnesium (Mg) 0.05%, zinc (Zn) 0.2%, aluminium (Al) surplus, main Alloying Design principle is by adding elemental silicon in the high Al-Mn alloy, copper is realized the mechanics reinforcement, after adding an amount of element zinc raising corrosion resistance and adopting melting and casting+hot rolling+cold-rolling process preparation, pass through temper and commercial soldering thermal treatment again.Through test, its tensile strength, yield strength, unit elongation all are improved largely, the method for preparing of the present invention, make the brazing coating alloy plate material have more superior mechanical strength and better electrochemical corrosion potential, be a kind of high strength, anticorodal has a good application prospect.
