EN 4005:2007

Overview

EN 4005:2007 (CEN) is a European aerospace material standard that defines requirements for aluminium alloy AL‑P5052‑O - sheet and strip with thicknesses 0.3 mm ≤ a ≤ 6 mm. Part of the Aerospace series of metallic material standards, EN 4005:2007 standardizes composition, form, production method, dimensional limits and basic mechanical property limits for this wrought aluminium alloy intended for aerospace applications.

Key topics and requirements

• Material designation: Aluminium alloy AL‑P5052‑O (sheet and strip).
• Form and production: Rolled sheet and strip; thickness range 0.3–6 mm.
• Delivery condition: Specified as O (see EN 4400-2 for delivery/heat treatment details).
• Chemical composition (maximums):
  • Si 0.25%, Fe 0.40%, Cu 0.10%, Mn 0.10%
  • Mg 2.8%, Cr 0.35%, Zn 0.10%
  • Other individual elements ≤ 0.05%, total others ≤ 0.15%
  • Aluminium balance (base).
• Mechanical properties (ambient temperature):
  • Proof stress Rp0.2 ≥ 65 MPa for both thickness ranges
  • Tensile strength Rm = 170–215 MPa
  • Elongation A (A50 mm):
    • ≥ 16% for 0.3 ≤ a ≤ 0.8 mm
    • ≥ 19% for 0.8 < a ≤ 6 mm
• Testing, inspection and sampling: Test specimens, test pieces and inspection procedures referenced to EN 4400‑2 (Aerospace aluminium technical specification).
• Product qualification: Qualification programme to be agreed between manufacturer and purchaser.
