EN AW-2024: The aerospace aluminum alloy 2024 clad (WL 3.1364) and unclad (WL 3.1354) for highly stressed parts

Aluminum is typically the material of choice when high load-bearing capacity and a low weight are required: Low density, reliable corrosion resistance and thermal conductivity are key material properties in a wide range of industries. The addition of alloying elements can significantly increase the originally low strength of pure aluminum.

The aluminum alloy EN AW-2024 has excellent mechanical properties, a high resistance to mechanical stress and is used as WL 3.1364 (EN AW-2024 clad) and WL 3.1354 (EN AW-2024 unclad) in the aerospace, automotive as well as electrical industries. As an experienced metal specialist, robemetall can supply you with WL 3.1354 or WL 3.1364 quickly and in a wide variety of shapes!

EN AW-2024 clad (WL 3.1364) and unclad (WL 3.1354)

Alloy 2024 with copper as well as magnesium is an optimized variant of the EN AW-2017 alloy. Thanks to its increased strength values and mechanical resistance, EN AW-2024 is used primarily in aerospace.

Due to the contained copper, the corrosion resistance of the duralumin alloy EN AW-2024 unclad (WL 3.1354) is rather poor – thanks to the application of a higher-quality metal layer, the corrosion protection of EN AW-2024 clad (WL 3.1364) is higher.

The basic properties of EN AW-2024

  • Very high mechanical strength & good mechanical properties
  • Suitable for use at higher temperatures
  • Good weldability (resistance welding / spot-welding / electron-beam welding)
  • Suitable for brazing and cold joint
  • Good properties for cold forming
  • Weather resistant with additional coating (WL 3.1364)
