Overview

EN 4203:2005 (CEN) specifies requirements for the aerospace sheet material Aluminium alloy AL‑P8090‑T89 in the thickness range 0.6 mm ≤ a ≤ 6 mm. Part of the EN aerospace metallic materials series, this standard covers designation, chemical limits, production and delivery conditions, mechanical properties, microstructure and inspection requirements for aluminium sheet used in aerospace applications.

Key topics and technical requirements

  • Material and form
    • Aluminium alloy designation: AL‑P8090‑T89
    • Form: rolled sheet, thickness range 0.6–6 mm
  • Chemical composition
    • Limits are specified for Si, Fe, Cu, Mn, Mg, Cr, Zn, Li, Zr, Ti and aluminium (base). Example maximums given in the standard include Si ≤ 0.20%, Fe ≤ 0.30%, Cu ≤ 1.6%, Mg ≤ 1.3%, Li ≤ 2.7%, Zr ≤ 0.16% (see EN 4203:2005 for full table).
  • Delivery conditions and heat treatment
    • Delivery tempers include T39 and T89 with defined solution treatment (525–535 °C / water quench to ≤ 40 °C), controlled stretch +4.0% to +4.5%, and, for T89, an artificial ageing step ≈162–168 °C for 44–46 h.
  • Mechanical properties
    • Minimum mechanical values specified: proof stress (Rp0.2) ≥ 340 MPa, tensile strength (Rm) ≥ 440 MPa, elongation A ≥ 6% (test direction LT, ambient temperature).
  • Microstructure and toughness
    • Microstructural requirements (degree of recrystallization) and fracture toughness references are included; the standard refers to EN 4400‑2 for test methods and includes a fracture toughness guidance (K) ≈ ≥ 40 MPa·m^0.5.
  • Corrosion and inspection
    • Exfoliation corrosion limits, batch uniformity, dimensional and marking inspections are specified, with many test and inspection procedures referenced to EN 4400‑2.

Applications and users

  • Intended for aerospace structural sheet applications where a high strength‑to‑weight aluminium alloy is required.
  • Primary users:
    • Aerospace material engineers and designers specifying sheet metallurgy
    • Manufacturers and suppliers of aerospace aluminium sheet
    • Procurement, quality and certification teams verifying conformity to material standards
    • Test laboratories performing mechanical, microstructural and corrosion testing
