Alcoa 2024 was introduced by Alcoa in 1931 as the first alloy to have a yield strength approaching 345 MPa (50 ksi). With relatively good fatigue resistance in plate forms, alloy 2024 continues in many aerospace structural applications. This datasheet provides information on composition, physical properties, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as surface treatment. Filing Code: AL-372. Producer or source: Alcoa Mill Products Inc.
