Abstract
A clad aluminum alloy material having high strength and high corrosion resistance for a heat exchanger, which is composed of a core material made of an aluminum alloy consisting of 0.3 to 2.0% of Mn, 0.25 to 0.8% of Cu, 0.05 to 1.0% of Si and 0.5% or less of Mg with the balance consisting of Al and unavoidable impurities; a sacrificial anode material bonded to one surface of the core material, the sacrificial anode material being made of an aluminum alloy consisting of 1.0 to 2.5% of Mg and 0.05 to less than 0.20% of Si with the balance consisting of Al and unavoidable impurities; and a cladding bonded to the other surface of the core material, the cladding being made of a brazing filler metal consisting of an Al-Si-base aluminum alloy. In the clad aluminum alloy materials, the core material may further include 0.35% or less of Ti and the sacrificial anode material may further include 3.0% or less of Zn or at least one member selected from the group consisting of 0.2% or less of In, 0.2% or less of Sn and 0.2% or less of Ga.
