The aluminum or aluminum alloy material has an aluminum or aluminum alloy substrate, a hydrophilic film with a thickness of 0.1 to 10 mu m formed on the substrate, and a water soluble resin film with a thickness of 0.1 to 10 mu m formed on the hydrophilic film. The hydrophilic film contains, based on 100 pts.mass of at least one kind selected from the group consisting of polyacrylic acid and polyacrylates, 1 to 200 pts.mass of water soluble resin having hydroxyl groups in molecules, and 1 to 20 pts.mass of at least on kind selected from the group consisting of phosphoric acid and phosphate compounds. The water soluble resin film has hydroxyl groups in molecules. The invention provides for a heat exchanger fin which can maintain hydrophilic properties over a long period of time even in a peculiar indoor environment where the concentration of contaminants in the indoor air constantly remains high, and has excellent press formability as well, and to provide a fin for a heat exchanger. |
