2024 aluminum alloy is a kind of high-strength duralumin, which belongs to the Al-Cu-Mg series aluminum alloys. It is mainly used to make various high-load parts and components. It can be heat treated and strengthened, and its plasticity is medium in the quenched and just quenched state. 2024 aluminum alloy can be strengthened by heat treatment. It has moderate plasticity in quenched and just quenched conditions. It has good spot welding and has a tendency to form intergranular cracks when using gas welding. The alloy has good machinability after quenching and cold work hardening. After annealing Low machinability: The corrosion resistance is not high. Anodizing and painting methods are often used, or the surface is coated with aluminum to improve its corrosion resistance. Uses are mainly used to make various high-load parts and components (but not stamping forgings) such as aircraft skeleton parts, skins, bulkheads, ribs, spars, rivets and other working parts below 150°C.

2024 aluminium alloy is an aluminium alloy, with copper as the primary alloying element. It is used in applications requiring high strength to weight ratio, as well as good fatigue resistance. It is weldable only through friction welding, and has average machinability. Due to poor corrosion resistance, it is often clad with aluminium or Al-1Zn for protection, although this may reduce the fatigue strength. In older systems of terminology, 2XXX series alloys were known as duralumin, and this alloy was named 24ST. 2024 is commonly extruded, and also available in alclad sheet and plate forms. It is not commonly forged.

2024-O
2024-O temper aluminium has no heat treating. It has an ultimate tensile strength of 140–210 MPa (21–30 ksi), and maximum yield strength of no more than 97 MPa (14,000 psi). The material has elongation (stretch before ultimate failure) of 10–25%, this is the allowable range per applicable AMS specifications.

2024-T3
T3 temper 2024 sheet has an ultimate tensile strength of 400–430 MPa (58–62 ksi) and yield strength of at least 270–280 MPa (39–40 ksi). It has an elongation of 10–15%.

2024-T4
Solution treated and naturally aged.

2024-T5
Cooled from hot working and artificially aged (at elevated temperature)
