2024-T4 aluminum is 2024 aluminum in the T4 temper. To achieve this temper, the metal is solution heat-treated and naturally aged. It has the highest ductility compared to the other variants of 2024 aluminum.
The graph barss on the material properties cards below compare 2024-T4 aluminum to: 2000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bars means this is the highest value in the relevant set. A half-full bars means it’s 50% of the highest, and so on.
