Abstract: Cu-Al composite row was produced by continuous cast-rolling technique and metallurgical bonding interface was achieved. The composite row shows excellent mechanical property and conductivity: overall tensile strength of 102MPa, resistance rate of 0.0216Ωmm2/m. The composite annealing temperature and thermal cycling influencing on the interfacial bonding strength were researched. The microstructure of interface and the composite mechanism was analyzed by SEM, XRD and Metallurgical microscope.
