Abstract: Al/Cu composite sheet was fabricated using accumulative roll bonding(ARB) and electrodeposition. The thickness of the deposited copper layer and the microstructure and mechanical properties of the composite sheet were investigated. The results show that the thickness of the copper layer obtained by electrodeposition is relatively uniform and the bonding quality with the surface of the aluminum sheet is better. With the increase of ARB cycles, the interface bonding quality is getting better and better, and the copper layer in the composite sheet gradually shrinks or breaks, and finally becomes smaller and more uniformly distributed copper particles. The composite after four ARB cycles reaches the highest ultimate tensile strength(UTS) of 186.6 MPa, which is 2.72 times of that of annealed 1060 aluminum sheet.
