PROBLEM TO BE SOLVED: To provide an aluminum alloy-clad material for heat exchangers which has excellent erosion-corrosion resistance and general corrosion resistance, has high strength for thickness reduction, and is more particularly appropriate as the tube material for the heat exchangers of automobiles made of the aluminum alloy, such as radiators, heaters and oil coolers joined by inert gaseous atmosphere brazing using a fluoride-based flux and caeside-based flux.;SOLUTION: The aluminum alloy clad material is a three-layered clad material of the aluminum alloy formed by cladding a brazing filler metal having the erosion-corrosion resistance via an intermediate material on one side of a core material, in which the clad material is composed of the aluminum ally containing at least 0.8 to 1.8% Mn, the intermediate material is composed of the aluminum alloy containing at least 0.6 to 1.8% Mn, 0.5% to ≤1.5% Fe, 0.6 to ≤1.1% Si, and 0.5 to 10% Zn, and the brazing filler metal having the erosion-corrosion resistance is composed of the aluminum alloy containing at least 3 to 13% Si.;COPYRIGHT: (C)2006,JPO&NCIPI
