摘　　要：试验研究了不同状态的包覆层对汽车热交换器用铝合金复合箔抗下垂性能的影响。结果表明,铸造状态的包覆层制备的复合材料与热轧状态的包覆层制备的复合材料相比,前者包覆层中的Si元素只具备浓度梯度,在轧制复合过程中Si原子从包覆层向芯层的扩散程度要小于后者的,并且前者的抗下垂性能要优于后者。The experiment was conducted to investigate the influence of cast structure of clad layers on sagging resistance of aluminum composite foils for automobile exchangers. The results show that the composite prepared by clad layers with cast structure has only silicon gradient compared to that with hot rolling structure thus diffusion of silicon from clad layer to core layer is less than the latter and sagging resistance is superior to the latter.
