Duralumin (also called duraluminum, duraluminium or dural) is the trade name of one of the earliest types of age-hardenable aluminium alloys. The main alloying constituents are copper, manganese, and magnesium. A commonly used modern equivalent of this alloy type is AA2024, which contains 4.4% copper, 1.5% magnesium, 0.6% manganese and 93.5% aluminium by weight. Typical yield strength is 450 MPa (65 ksi), with variations depending on the composition and temper.
Applications
List of typical uses for the wrought Al-Cu alloys:[1]
2011: Wire, rod, and bar for screw machine products. Applications where good machinability and good strength are required. 2014: Heavy-duty forgings, plate, and extrusions for aircraft fittings, wheels, and major structural components, space booster tankage and structure, truck frame and suspension components. Applications requiring high strength and hardness including service at elevated temperatures. 2024: Aircraft structures, rivets, hardware, truck wheels, screw machine products, and other miscellaneous structural applications. 2036: Sheet for auto body panels. 2048: Sheet and plate in structural components for aerospace application and military equipment. 2141: Plate in thicknesses of 40 to 150 mm (1.6 to 5.9 in) for aircraft structures. 2218: Forgings; aircraft and diesel engine pistons; aircraft engine cylinder heads; jet engine impellers and compressor rings. 2219: Welded space booster oxidizer and fuel tanks, supersonic aircraft skin and structure components. Readily weldable and useful for applications over temperature range of -270 to 300 °C (-454 to 572 °F). Has high fracture toughness, and the T8 temper is highly resistant to stress-corrosion cracking. 2618: Die and hand forgings. Pistons and rotating aircraft engine parts for operation at elevated temperatures. Tire molds.
