2024 is commonly extruded, and also available in alclad sheet and plate forms. It is not commonly forged (the related 2014 aluminium alloy is, though).
Aluminium alloy 2024 has a density of 2.78 g/cm3 (0.1 lb/in3), electrical conductivity of 30% IACS, Young’s Modulus of 73 GPa (10.6 Msi) across all tempers, and begins to melt at 500 °C (932 °F).
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 Aluminum Alloy States:
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.
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%.
T4 Solution treated and naturally aged.
T5 Cooled from hot working and artificially aged (at elevated temperature)
T351 temper 2024 plate has an ultimate tensile strength of 470 MPa (68 ksi) and yield strength of 280 MPa (41 ksi). It has elongation of 20%.
