PROBLEM TO BE SOLVED: To provide an aluminum alloy material with excellent corrosion resistance, and to provide a plate-fin heat exchanger and a plate heat exchanger using the aluminum alloy material for a heat transfer portion with a fluid having corrosiveness as a coolant.;SOLUTION: The surface of an aluminum alloy material used for a plate-fin heat exchanger, a plate heat exchanger or the like using a heat transfer portion with a liquid having corrosiveness as a coolant is provided with an organic phosphoric acid underlying coating. The surface thereof is further provided with a fluorocarbon resin coating with the average thickness of 1 to 100 μm by coating thickness after drying. The aluminum alloy material has improved durability of coating adhesion and excellent corrosion resistance to a liquid having corrosiveness such as seawater.;COPYRIGHT: (C)2008,JPO&INPIT
