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.
An aluminum alloy clad material comprising 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 consists of 0.6 to 2.0 mass % of Mn and 0.4 mass % or less of Cu, optionally, one or more of 0.01 to 0.3 mass % of Ti, 1.5 mass % or less of Si and 0.7 mass % or less of Fe, with the balance being aluminum and unavoidable impurities, the inner cladding material being formed of an Al—Mn—Cu alloy that comprises 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 comprises 0.5 to 10.0 mass % of Zn, with the balance being aluminum and unavoidable impurities.
