EN 2638:2019 - Aerospace series - Aluminium alloy 2024- - T3 - Extruded bar and section - 1,2 mm ≤ (a or D) ≤ 150 mm with coarse peripheral grain control

Overview

EN 2638:2019 specifies requirements for Aluminium alloy 2024‑T3 in extruded bars and sections for aerospace use. It covers products with cross‑section or diameter in the range 1.2 mm ≤ (a or D) ≤ 150 mm and requires coarse peripheral grain control. The standard is part of the CEN/ASD‑STAN aerospace series and defines material, heat‑treatment, mechanical properties, inspection and relevant test methods for aerospace applications.

Key topics and requirements

  • Material and form: Aluminium alloy 2024‑T3, extruded bars and sections (including L, channel, T and round/square/rectangular profiles referenced via EN 2047–EN 2050, EN 2134 and EN 2341).
  • Size range: Cross‑section or diameter 1.2 mm to 150 mm.
  • Heat treatment / delivery condition: Delivery condition T3 - solution treated at 495 ± 5 °C with water quench (θ ≤ 40 °C), cold‑worked and naturally aged t ≥ 5 days. Delivery condition code U is noted.
  • Mechanical properties (minimums vary by size category):
    • 0.2% proof stress (Rp0.2): roughly 320–340 MPa (size dependent).
    • Tensile strength (Rm): roughly 440–470 MPa.
    • Elongation (A): 9–12% (A50 mm typical).
    • Hardness: indicated ~120 HB (informational).
  • Microstructure and inspection: Requires coarse peripheral grain control; grain size referenced to EN 2070‑3 (Level A).
  • Electrical conductivity: Informational range 17–20 MS/m (EN 2004‑1).
  • Testing & inspection: References to EN 2004‑1 and the EN 2070 series for test specimens, dimensional and marking inspections. Product qualification programs are to be agreed between manufacturer and purchaser.

Applications and users

  • Applications: Structural aerospace components, machined parts, extruded profiles and bars used in airframe and subsystem assemblies where 2024‑T3 properties are required. Typical uses include fittings, stiffeners, brackets and other load‑bearing extruded elements.
  • Who uses this standard: Aerospace material engineers, procurement specialists, extrusion manufacturers, quality/inspection teams, design engineers, and certification bodies who require consistent mechanical, metallurgical and dimensional characteristics for aluminium 2024‑T3 extrusions.

Related standards

  • EN 2047–EN 2050 (extruded section dimensions: L, beaded L, channel, T)
  • EN 2134, EN 2341 (round, square/rectangular extruded bar dimensions)
  • EN 2070‑1 / EN 2070‑3 (technical specifications and grain size)
  • EN 2004‑1 (electrical conductivity test)
  • EN 4258, EN 4500‑2 (series organization and drafting rules)

EN 2638:2019 is essential for ensuring consistent, auditable specification of 2024‑T3 extruded bars and profiles with coarse peripheral grain control in aerospace supply chains.
