Research on Roll Welding Process of Cu/Al Composite Plates

Abstract:

Cu/Al composites have the advantage of both copper and aluminum, i.e., the high electrical conductivity, high thermal conductivity, and low contact resistance of copper; the lightweight and corrosion resistant of aluminum. Roll welding is one common method to produce Cu/Al composite plates. The effects of rolling reduction ratio and annealing temperature on combined strength are analyzed by experiments. The results demonstrate that the combined strength increases with the increase of rolling reduction ratio, and at around 300°C the combined strength achieves the maximum value. The reason is then analyzed respectively. The results are helpful for understanding the Cu/Al combing mechanism, and are useful for improving the producing process of Cu/Al composite plates.
