2024 aluminium alloy

 

Aluminium alloy 2024 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 poorcorrosion resistance, it is often clad with aluminium or Al-1Zn for protection, although this may reduce the fatigue strength. In older systems of terminology, this alloy was named 24ST.

2024 is commonly extruded, and also available in alclad sheet and plate forms. It is not commonly forged (the related 2014 aluminum alloyis, though).

Basic properties[edit]

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).

2024 aluminium alloy's composition roughly includes 4.3-4.5% copper, 0.5-0.6% manganese, 1.3-1.5% magnesium and less than a half a percent of silicon, zinc, nickel, chromium, lead and bismuth.

Mechanical properties

The mechanical properties of 2024 depend greatly on the temper of the material.

2024-O

2024-O temper aluminium has no heat treating. It has an ultimate tensile strength of 30-32 ksi (207-220 MPa), and maximum yield strengthof no more than 14,000 psi (96 MPa). 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 58-62 ksi (400-427 MPa) and yield strength of at least 39-40 ksi (269-276 MPa). It has an elongation of 10-15%.

2024-T4

Solution treated and naturally aged.

2024-T351

T351 temper 2024 plate has an ultimate tensile strength of 68 ksi (470 MPa) and yield strength of 41 ksi (280 MPa). It has elongation of 19%.

Uses

Due to its high strength and fatigue resistance, 2024 is widely used in aircraft structures, especially wing and fuselage structures under tension. Additionally, since the material is susceptible to thermal shock, 2024 is used in qualification of liquid penetrant tests outside of normal temperature ranges.
