Abstract

The present invention provides a high strength aluminum alloy suitable for use in the manufacture of a fin, said aluminum alloy containing at most 0.1% by weight of Si, 0.10 to 1.0% by weight of Fe, 0.1 to 0.50%
by weight of Mn, 0.01 to 0.15% by weight of Ti, and the balance of A~ and unavoidable impurities, intermetallic compounds having a diameter not larger than 0.1 µm being distributed within the metal texture of the alloy in a number density of at least 10/µm3. The present invention also provides a method of manufacturing a high strength aluminum alloy suitable for use in the manufacture of a fin, comprising the steps of heating to 430 to 580°C an aluminum alloy ingot of the composition noted above, applying a hot rolling treatment to said aluminum alloy ingot to obtain a plate material before the temperature of the aluminum alloy ingot is lowered by at most 50°C from the temperature immediately after the heating step, applying a cold rolling treatment to the resultant plate material such that the final rate of reduction in the thickness of the plate material is at least 80%, and applying a homogenizing annealing treatment to the cold rolled thin plate material at 250 to 320°C to cause intermetallic compounds having a diameter not larger than 0.1 µm to be distributed within the metal texture of the alloy in a number density of at least 10/µm3.
