Overview
EN 3553:2004 is a CEN (Aerospace series) standard that specifies requirements for aluminium alloy AL‑P2618A in the T6511 condition, manufactured as extruded bars and sections with a maximum cross‑section dimension (a or D) of ≤ 160 mm. It is intended for aerospace applications and may be used to supply material in the T6510 condition if the purchaser so specifies and the product is marked accordingly.
Key topics and technical requirements
- Material designation: Aluminium alloy AL‑P2618A (composition ranges and limits are defined in the standard).
- Product form: Extruded bars and sections, maximum dimension a or D ≤ 160 mm; three size groups: ≤10 mm, 10–100 mm, 100–160 mm.
- Delivery conditions: Primary delivery in T6511 (solution heat treatment, quench and controlled stretch, followed by artificial ageing). T6510 is permitted only by purchaser’s order.
- Heat treatment parameters (typical as shown):
- Solution temperature: 525 °C ≤ θ ≤ 535 °C / quench to ≤ 80 °C
- Controlled stretch: +1 % to ≤3 %
- Ageing: 187 °C to 205 °C for 16–24 h
- Note: Longer solution times (typically 4–24 h) may be required for this alloy.
- Mechanical properties (minimums by size group):
- Proof stress Rp0.2: ≥ 340 MPa (≤10 mm), ≥ 360 MPa (10–100 mm), ≥ 350 MPa (100–160 mm)
- Tensile strength Rm: ≥ 410 MPa, ≥ 420 MPa, ≥ 410 MPa (corresponding groups)
- Elongation A (50 mm): ≥ 5 % (≤10 mm), ≥ 6 % (other groups)
- Other controls & inspections:
- Tests, test-piece orientation and samples referenced to EN 4400‑3 (bar and section technical specification)
- Defect acceptance, dimensional and marking inspections, batch uniformity and extrusion back‑end defect requirements are addressed via EN 4400‑3.
- Typical physical data: Electrical conductivity is given as a typical value (e.g., ~18.0 MS/m for one condition and ~21.0 MS/m for another).
Applications and users
- Intended for aerospace manufacturers, suppliers, material engineers, procurement and quality assurance teams involved in structural and metallic components where a certified high‑strength extruded aluminium section is required.
- Typical uses include aerospace structural parts fabricated from extruded bars and profiles (up to 160 mm cross section) where controlled heat treatment and mechanical properties are critical.
