School of Materials & Metallurgy, Jilin University, Changchun 130022, China；2. School of Materials & Metallurgy, Yanshan University, Qin huangdao 066004, China. Correspondent: MOU Mou-mou, E-mail: )Abstract：The cold-rolling cladding process of composite aluminum alloy foil for automobile heat exchanger was investigated, as well as the effects of percentage reduction of first pass, clad sheet thickness and final annealing schedule on the microstructure and properties of the foil. The results showed that bonding the clad sheets A4045 to the core material A3003 on both sides succeeds initially when the percentage reduction is 30%~50% of first pass during cold rolling, and the thickness of both the clad sheets of the composite foil are basically the same. The best sagging resistance is available when the percentage reduction of final pass is 25%~35%. The annealing temperature should be controlled in the range from 320 to 400℃ before finish rolling, and the annealing time s...
