SIST EN 3552:2005 - Aerospace series - Aluminium alloy AL-P2618A-T6 or T62 - Clad sheet and strip - 0,4 mm <a <6 mm

Overview

EN 3552:2005 is a CEN/AECMA-STAN aerospace material standard that specifies the requirements for aluminium alloy AL‑P2618A in clad sheet and strip form for aerospace use. The standard covers material designation, delivery and use conditions, heat treatments, dimensional limits and key mechanical properties for thicknesses from 0.4 mm to 6 mm.

Key elements defined in the standard include:

  • Alloy: AL‑P2618A (wrought aluminium alloy for aerospace)
  • Forms: Clad sheet and strip, produced by rolling
  • Thickness (a): 0.4 mm ≤ a ≤ 6 mm (two ranges: 0.4–3 mm and >3–6 mm)
  • Delivery conditions / heat treatment codes: T6 and T62
  • Cladding: Typical cladding alloy designation AL‑P7072 and minimum cladding thickness by face

EN 3552:2005 sits within the EN aerospace metallic materials series and references EN 4400‑2 (sheet and strip technical specification), EN 4258 (series organisation) and EN 4500‑2 (rules for drafting aluminium standards).

Key Topics

  • Heat treatment parameters: Solution heat treatment and water quench (525 °C to 535 °C; WQ ≤ 40 °C) followed by artificial ageing. For T6 the ageing range is 180–205 °C for 16–24 h; T62 ageing is specified at 195–205 °C for 16–24 h.
  • Mechanical properties: Specified minimum values differ by thickness range:
    • For 0.4–3 mm: proof stress R_p0.2 ≥ 310 MPa; tensile strength R_m ≥ 390 MPa; elongation A ≥ 7% (50 mm)
    • For >3–6 mm: proof stress R_p0.2 ≥ 325 MPa; tensile strength R_m ≥ 395 MPa; elongation A ≥ 5% (50 mm)
  • Cladding thickness: Minimum cladding on each face is specified (for thinner gauges a larger % is required): e.g. ≥4% per face for the lower thickness range and ≥2% for the thicker range.
  • Testing and inspection: Test samples, specimen directions (LT), dimensional and marking inspection follow EN 4400‑2. Batch uniformity, electrical conductivity and other checks are referenced to EN 4400‑2.
  • Notes and limitations: The standard advises that repeated re-solution heat treatment is not recommended due to copper diffusion effects in the cladding which can affect elevated temperature properties.

Applications

EN 3552:2005 is intended for aerospace structural and component manufacture where a high-strength, clad aluminium sheet or strip is required. Typical benefits and uses include:

  • Certified procurement of aluminium sheet/strip for airframe and structural parts
  • Use where cladding is required for corrosion protection or solderability (AL‑P7072 cladding)
  • Specification basis for aerospace suppliers and purchasers to agree qualification and acceptance criteria

Product qualification programmes and specific procurement details are to be agreed between manufacturer and purchaser as noted in the standard.
