PROBLEM TO BE SOLVED: To provide a clad material excellent in corrosion resistance and used as the member for a heat exchanger. SOLUTION: One side of a core material having a compsn. contg. 0.8 to 1.8% Mn, furthermore contg. 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, one or >= two kinds among 0.05 to 0.2% Ti, 0.05 to 0.2% Zr, 0.05 to 0.5% V, 0.05 to 0.5% Cr and 0.01 to 0.2% Mg, and the balance Al with inevitable impurities is clad with an Al-Si brazing filler metal, and the other side of the core material is clad with a sacrificial anode material contg. one or >= two kinds among 1 to 10% Zn, 0.5 to 2.0% Mg, 0.05 to 0.5% Ti, 0.05 to 0.5% Zr, 0.05 to 0.5% V and 0.05 to 0.5% Cr, and the balance Al with inevitable impurities. |
