2024 is one of the best known of the high strength aluminum alloys. With its high strength and excellent fatigue resistance, it is used to advantage on structures and parts where good strength-to-weight ratio is desired. It is readily machined to a high finish. It is readily formed in the annealed condition and may be subsequently heat treated. Arc or gas welding is generally not recommended, although this alloy may be spot, seam or flash welded. Since corrosion resistance is relatively low, 2024 is commonly used with an anodized finish or in clad form ("Alclad") with a thin surface layer of high purity aluminum. Applications: aircraft structural components, aircraft fittings, hardware, truck wheels and parts for the transportation industry.
Alclad sheet must be masked before shearing to protect surface finish.

  • 1 Ratings A through E are relative ratings in decreasing order of merit, based on exposures to sodium chloride solution by intermittent spraying or immersion. Alloys with A and B ratings can be used in industrial and seacoast atmospheres without protection. Alloys with C, D and E ratings generally should be protected at least on faying surfaces.
  • 2 Ratings A through E are relative ratings in decreasing order of merit, based on exposures to sodium chloride solution by intermittent spraying or immersion. Alloys with A and B ratings can be used in industrial and seacoast atmospheres without protection. Alloys with C, D and E ratings generally should be protected at least on faying surfaces.
    In relatively thick sections, the rating would be E.
  • 3 Stress-corrosion cracking ratings are based on service experience and on laboratory tests of specimens exposed to the 3.5% sodium chloride alternate immersion test.
  • 4 Ratings A through D for Workability (cold), and A through E for Machinability, are relative ratings in decreasing order of merit.
  • 5 Ratings A through D for Weldability and Brazeability are relative ratings.
  • 6 A = Generally weldable by all commercial procedures and methods.
    B = Weldable with special techniques or for specific applications that justify preliminary trials or testing to develop welding procedure and weld performance.
    C = Limited weldability because of crack sensitivity or loss in resistance to corrosion and mechanical properties.
  • 7 A = Generally weldable by all commercial procedures and methods.
    B = Weldable with special techniques or for specific applications that justify preliminary trials or testing to develop welding procedure and weld performance.
    C = Limited weldability because of crack sensitivity or loss in resistance to corrosion and mechanical properties.
  • 8 A = Generally weldable by all commercial procedures and methods.
    B = Weldable with special techniques or for specific applications that justify preliminary trials or testing to develop welding procedure and weld performance.
