Overview

EN 4247:2005 (CEN) specifies requirements for aerospace-grade aluminium alloy AL‑P2024‑T42 in the form of rolled plate with thickness range 6 mm < a ≤ 140 mm. Part of the EN aerospace series prepared by AECMA‑STAN, this standard defines chemical composition limits, manufacture (rolled plate), delivery and use conditions, and key mechanical property requirements for aerospace applications.

Key topics and requirements

  • Material designation: Aluminium alloy AL‑P2024‑T42 (rolled plate).
  • Form and dimensions: Plate, rolled; applicable thicknesses 6 mm < a ≤ 140 mm.
  • Chemical composition (typical limits):
    • Cu: 3.8–4.9%
    • Mg: 1.2–1.8%
    • Mn: 0.30–0.9%
    • Si, Fe: each ≤ 0.50%
    • Cr ≤ 0.10%, Zn ≤ 0.25%, Ti ≤ 0.15%
    • Maximum for any impurity ≈ 0.05%, total impurities ≈ 0.15% (Values reproduced from the standard’s composition table.)
  • Delivery condition: Code F (as manufactured).
  • Use condition (T42): Specified heat treatment sequence appears in the standard: solution heat treatment at ≈ 490–500 °C, water quench to ≤ 40 °C, then natural aging at ambient for a specified period (document indicates t ≈ 5 days). Users should consult the full standard for exact procedural and acceptance criteria.
  • Mechanical properties (min. values depend on thickness):
    • Tensile strength Rm: ≥ 420 MPa (thinner plates) down to ≥ 380 MPa (thicker plates)
    • Proof stress Rp0.2: ≥ 260 MPa down to ≥ 245 MPa
    • Elongation A (%): ≥ 12% down to ≥ 7% (varies by thickness band)
  • Testing and inspection: Test-piece orientation LT, ambient test temperature, and references to EN 4400‑1 for plate technical specification, testing, marking and dimensional inspection.

Applications and users

  • Primary users: aerospace manufacturers, materials engineers, procurement/specification teams, quality/acceptance inspectors, and OEMs sourcing aluminium plates for aircraft structures.
  • Typical uses: structural aircraft components and assemblies where 2024‑T42 material properties (high strength, fatigue resistance) are required. Suitable for designers and buyers specifying rolled aerospace plate to EN requirements.
