  • Aluminum alloy clad material and heat exchanger that includes tube obtained by forming the clad material
    Patent number: 10094629
    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.

  • ALUMINUM ALLOY CLAD MATERIAL AND HEAT EXCHANGER THAT INCLUDES TUBE OBTAINED BY FORMING THE CLAD MATERIAL
    Publication number: 20160290743
    Abstract: An aluminum alloy clad material produces a heat exchanger tube that exhibits excellent outer-side corrosion resistance when formed into a tube. The 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.
