An aluminum alloy clad material includes a core material, one side being clad with cladding material, the other side being clad with cladding material, the core material including an aluminum alloy that includes 0.5 to 1.8% of Mn, and limited to 0.05% or less of Cu, with the balance being Al and unavoidable impurities, the cladding materialincluding 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 materialincluding an aluminum alloy that includes 3 to 13% of Si, and limited to 0.05% or less of Cu, with the balance being Al and unavoidable impurities, wherein the Si content X (%) in the cladding materialand the Si content Y (%) in the cladding materialsatisfy the value (Y&#x2212;X) is &#x2212;1.5 to 9%.

Aluminum alloy cladding material for heat exchanger

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&#x2014;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&#x2014;Mn&#x2014;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&#x2014;Zn alloy that includes 0.5 to 10.0 mass % of Zn, with the balance being aluminum and unavoidable impurities.
