The composite was produced by pouring melt Al into solid Cu pipe. Microstructure, mechanical properties and Cu-Al composition distribution in Cu/Al composite interface were studied in the paper. The experimental results show that Cu and Al diffuse to each other, which the Cu/Al interface zone is formed. Moreover, there are lots of Cu-Al phase appearing in the Cu/Al interface zone. Furthermore, the influences of annealing temperature on the peal strength of Cu/Al interface were tested, in which the peel strength of the Cu/Al interface zone reaches the highest point to 15 MPa at 350°C and then decreases with the annealing temperature increases. In addition, the width of the diffusing layer and the average grain size of the Cu/Al interface zone increase with the annealing temperature increases.
