2024 Aluminum Sheet and Plate

Grade: 2024

Coil: 0.3mm-3.0mm

Sheet: 0.3mm-300mm

Width: 50mm-2000mm

Standard: ASTM, AMS, BS etc.

2024 is a heat treatable aluminum copper magnesium alloy widely used for aircraft sheet and plate. It offers high strength, useful fatigue performance and good machinability. Common products include T3 sheet and T351 plate, with stretching used to reduce residual stress in plate. Bare material has limited corrosion resistance compared with commercially pure aluminum, so protective finishes or Alclad products are often specified. Fusion welding is generally unsuitable for critical structural assemblies; mechanical fastening is common.
