Abstract: An aluminum alloy clad material includes a core material, an inner cladding material, and a sacrificial anode material, one side of the core material being clad with the inner cladding material, the other side of the core material being clad with the sacrificial anode material, the core material being formed of an Al—Mn alloy that includes 0.6 to 2.0 mass % of Mn and 0.4 mass % or less of Cu, with the balance being aluminum and unavoidable impurities, the inner cladding material being formed of an Al—Mn—Cu alloy that includes 0.6 to 2.0 mass % of Mn and 0.2 to 1.5 mass % of Cu, with the balance being aluminum and unavoidable impurities, and the sacrificial anode material being formed of an Al—Zn alloy that includes 0.5 to 10.0 mass % of Zn, with the balance being aluminum and unavoidable impurities.

Abstract: A three-layer clad material includes a core material, a cladding material 1, and a cladding material 2, the core material including an aluminum alloy that includes 0.5 to 1.8% of Mn, and either or both of more than 0.05% and less than 0.2% of Cu, and 0.05 to 0.30% of Ti, with the balance being Al and unavoidable impurities, the cladding material 1 including an aluminum alloy that includes 3 to 10% of Si, and 1 to 10% of Zn, with the balance being Al and unavoidable impurities, and the cladding material 2 including an aluminum alloy that includes 3 to 13% of Si, and 0.05% or less of Cu, with the balance being Al and unavoidable impurities, wherein the Si content X (%) in the cladding material 1 and the Si content Y (%) in the cladding material 2 satisfy the value (Y-X) is −1.5 to 9%.
