SIST EN 4004:2009

Overview

EN 4004:2007 specifies requirements for the aerospace series aluminium alloy AL‑P3103‑H16 in the form of sheet and strip with thickness 0.4 mm ≤ a ≤ 6 mm. Published by CEN and prepared within the ASD‑STAN framework, this standard defines chemical composition limits, production form, delivery condition (H16), and key mechanical properties and test directions needed for aerospace use. It is part of the EN metallic-materials series for aerospace applications and is intended to be applied alongside the referenced technical specification EN 4400‑2.

Key topics and technical requirements

• Material designation: Aluminium alloy AL‑P3103‑H16, rolled sheet and strip.
• Thickness range: 0.4 mm to 6 mm.
• Delivery condition: H16 (work‑hardened and partly annealed as specified).
• Chemical composition (maximums):
  • Si ≤ 0.50%, Fe ≤ 0.70%, Cu ≤ 0.10%, Mn ≤ 1.50%, Mg ≤ 0.30%, Cr ≤ 0.10%, Zn ≤ 0.20%
  • Ti and Zr: each ≤ 0.05%, combined ≤ 0.15%; remainder aluminium.
• Mechanical properties (by thickness range):
  • Proof stress Rp0.2 ≥ 135 MPa (all thicknesses)
  • Tensile strength Rm = 160–195 MPa (all thicknesses)
  • Elongation A (A50 mm): ≥ 2% (0.4–0.8 mm), ≥ 3% (0.8–1.3 mm), ≥ 4% (1.3–6 mm)
• Test direction and conditions: Test pieces taken in LT direction; tests at ambient temperature per EN 4400‑2.
• Inspections & product qualification: Dimensional, marking and external defect inspections and product qualification procedures are handled in accordance with EN 4400‑2 or by agreement between manufacturer and purchaser.

Applications and who uses this standard

• Primary audience: aerospace material specifiers, procurement specialists, manufacturers of aircraft metallic components, quality managers, and certification bodies.
• Practical use: EN 4004:2007 is used to ensure consistent material quality for aerospace sheet and strip made from AL‑P3103‑H16 when specifying purchases, preparing material data sheets, performing incoming inspections, and agreeing qualification/testing programs with suppliers.
• Benefits: Provides clear, harmonized limits for chemistry and mechanical performance, enabling interchangeability, traceability and conformity with aerospace material management practices.
