PROBLEM TO BE SOLVED: To provide a clad material excellent in corrosion resistance and used as the member for structural purpose such as a heat exchanger or the like. SOLUTION: One side of a core material having a compsn. contg. 0.8 to l.8% Mn, one or >= two kinds among 0.5 to 1.5% Fe, 0.1 to 1.0% Si and 0.1 to 1.0% Cu, contg., at need, 0.05 to 0.2% Ti, 0.05 to 0.2% Zr and 0.01 to 0.2% Mg, and the balance Al with inevitable impurities is clad with an Al-Si or Al-Si-Zn brazing filler metal, and the other side of the core material is clad with a sacrificial anode surface material having a compsn. contg. one or >=two kinds among 1 to 10% Zn, 0.01 to 0.5% Co, 0.1 to 2.0% Ni and 0.1 to 1.5% Mn, and the balance Al with inevitable impurities. |
