Abstract

See full text

An aluminum alloy fin material for a heat exchanger is made of an aluminum alloy including 0.05 mass % to 0.5 mass % of Si, 0.05 mass % to 0.7 mass % of Fe, 10 mass % to 2.0 mass % of Mn, 0.5 mass % to 1.5 mass % of Cu, and 3.0 mass % to 7.0 mass % of Zn, with the balance being Al and unavoidable impurities. In an L-ST plane thereof, second-phase grains having an equivalent circle diameter equal to or more than 0.030 μm and less than 0.50 μm have a perimeter density of 0.30 μm/μm2 or more, second-phase grains having an equivalent circle diameter equal to or more than 0.50 μm have a perimeter density of 0.030 μm/μm2 or more, and specific resistance thereof at 20° C. is 0.030 μΩm or more.
