PROBLEM TO BE SOLVED: To provide a method of brazing Cu and Al to obtain a member having both the lightweight property of Al and the excellent heat conductivity and electric conductivity of Cu. SOLUTION: In a method of brazing Cu 1 and Al 2, the composite coating of Al 8 is applied on a base material of Cu 1 with Ni 5 as an intermediate material and Al 8 as a skin, and the brazing is achieved using an Al-Si brazing filler metal 6 with Al as joining surfaces with each other. At least one kind among Fe, Co, Ta, Mo, Nb, W, Ti, Zr, Hf and an alloy thereof can be used in place of Ni 5 for the intermediate material. |
