Development of cladding brazing aluminum foil

In recent years, with the worsening of the global energy crisis, the automotive industry has focused on the development of lightweight materials to solve this problem. Because of its light weight, abundant resources and low price, aluminum alloy has become the first choice for automobile lightweight. As an important part of automobiles, radiators began to be gradually made of aluminum, in order to reduce the weight of automobiles and reduce costs. The three layer cladding / composite brazing aluminum foil is widely used as the raw material for fin in radiator. The processing technology and working environment of automotive heat exchanger require cladding / composite brazing aluminum foil to have appropriate strength, good droop resistance and corrosion resistance. However, the performance of cladding / composite brazing aluminum foil for automotive radiator is poor and unstable, which affects the service life of radiator. Therefore, it is of great significance to search for the influencing factors and influencing mechanism of the properties of cladding / composite brazed aluminum foil.





At present, the cladding / composite brazing aluminum foil dozens of households in the rapid development of automobile production has shown a good application prospect.
