Aluminum Sheet
2024 Aluminum Sheet
2024 Aluminum Sheet
One of the most common high-strength aluminium alloys.
The 2024 aluminium sheet has both high strength and excellent fatigue resistance. Due to its relatively low corrosion resistance, aluminium alloy 2024 is usually anodised or clad in the form of a thin surface layer of high purity aluminium (“Alclad”).
Typical applications for 2024 aluminium sheets are fuselage and wing skins, fairings, aircraft structures, and repair and restoration.

Typical Applications
2024 alloy, a high-strength hard aluminium, can be heat treated and strengthened, in the quenched and just quenched state plasticity is medium, spot welding good, with gas welding has the tendency to form intergranular cracks, the alloy in the quenching and cold hardening of its machinability is still good after annealing machinability is low, corrosion resistance is not high. It is mainly used for making various high load parts and components (but not including forgings for stamping) such as aircraft skeleton parts, skins, spacers, wing ribs, wing beams, rivets and other working parts below 150°C.
