Abstract
An aluminum alloy for use in a plate-fin heat exchanger having a heat transfer portion with seawater as a coolant includes an organic phosphonic acid underlying coating disposed on the surface of the aluminum alloy and a fluorocarbon resin coating disposed on the organic phosphonic acid underlying coating, the fluorocarbon resin coating having an average thickness of 1 to 100 μm after drying. The aluminum alloy has improved durability of coating adhesion and excellent seawater corrosion resistance.
