EN 3474:2005 - Aerospace series - Aluminium alloy AL-P2024-T81 - Sheet and strip - 0,25 mm <a <6 mm

Overview

EN 3474:2005 specifies requirements for the aerospace aluminium alloy AL-P2024-T81 in the form of sheet and strip with thicknesses from 0.25 mm to 6 mm. Prepared within the AECMA/CEN aerospace series, this standard defines essential material parameters, delivery conditions and inspection requirements to ensure consistent performance for aircraft structural applications.

Key facets of the standard include material designation, permitted production form (rolled sheet and strip), delivery tempers, heat-treatment regimes and referenced test methods.

Key Topics

  • Alloy and form: AL-P2024-T81 supplied as rolled sheet and strip for aerospace use (0.25 ≤ a ≤ 6 mm).
  • Chemical composition: Limits are specified for common alloying elements (Si, Fe, Cu, Mn, Mg, Cr, Zn, Ti, Al). For example, copper is a principal alloying element (typical range in the standard: ~3.8–4.9%). Silicon and iron have low maximum limits (≈0.50%). Magnesium and manganese ranges are also defined.
  • Delivery conditions and tempers: Delivery conditions include T31 and T81 tempers with defined solution, quench and ageing steps. The T81 condition is the specified use condition for many aerospace parts.
  • Mechanical properties: The standard gives minimum mechanical requirements such as proof stress and tensile strength (e.g., R_p0.2 and R_m values) and minimum elongation criteria appropriate for structural applications.
  • Physical and inspection values: Typical electrical conductivity values and hardness control limits are reported for relevant tempers. Inspection, marking and dimensional tolerances reference EN 4400-2.
  • Referenced test method standards: The standard mandates use of EN 4400-2 for sheet and strip technical specification and EN 4500-2 for presentation rules.

Applications

EN 3474:2005 is oriented to aerospace manufacturing and quality assurance. Practical applications include:

  • Aircraft primary and secondary structural skins
  • Fuselage and wing panels where high-strength Al-Cu alloys are required
  • Aerospace components requiring controlled temper and post-heat-treatment properties
  • Procurement specifications for manufacturers and purchasers to ensure batch uniformity and traceability

Benefits for users include predictable mechanical performance, conformity with industry testing and inspection regimes, and reduced supply-chain risk when purchasing AL-P2024-T81 sheet and strip.

Related Standards

  • EN 4400-2 - Aerospace series: Aluminium and aluminium alloy wrought products - Part 2: Sheet and strip (technical specification references for tests and samples).
  • EN 4258 - Organization of metallic material standards in the aerospace series.
  • EN 4500-2 - Rules for drafting and presentation of material standards (specific rules for aluminium alloys).

For procurement, manufacturing and quality-control teams, EN 3474:2005 provides a concise, harmonized specification to ensure AL-P2024-T81 sheet and strip meet aerospace industry expectations. For full implementation, consult the cited normative references and coordinate qualification programmes between manufacturer and purchaser as indicated in the standard.
