Overview
EN 3872:2005 (CEN) is an aerospace material standard that defines the requirements for die-forged components made from aluminium alloy AL‑R39002 in temper H112, with maximum cross-section dimension a ≤ 200 mm. It is part of the EN aerospace metallic materials series and is intended for use where high-strength, forged aluminium parts are required in aerospace applications.
Key topics and technical requirements
- Material designation: Aluminium alloy AL‑R39002, delivered in temper H112 (delivery condition code U).
- Form and size: Die forgings produced from forging stock (see EN 4292), with a ≤ 200 mm.
- Mechanical properties (ambient temperature) - direction-dependent requirements:
- Proof stress Rp0.2: ≥ 370 MPa (L), ≥ 360 MPa (LT), ≥ 350 MPa (ST).
- Tensile strength Rm: ≥ 455 MPa (L), ≥ 445 MPa (LT), ≥ 435 MPa (ST).
- Elongation A: ≥ 6% (L), ≥ 5% (LT), ≥ 3% (ST).
- Fracture toughness (K_IC): Orientation-specific minima for a ≤ 200 mm - ≥ 26, ≥ 25, ≥ 24 MPa·m^0.5 (as specified per orientation).
- Density: Specified per EN 6018 (document shows ρ ≤ 2.60 kg/dm^3).
- Testing, inspection and qualification: Test samples, inspection procedures, batch uniformity, external/internal defect criteria and product qualification follow EN 2082‑3 and related aerospace test methods. A qualification programme is to be agreed between manufacturer and purchaser.
- Reference framework: Prepared according to EN 4500‑2 and organized within the EN aerospace series (see EN 4258 for series structure).
Applications and who uses this standard
- Primary users: aerospace manufacturers, forging suppliers, materials and design engineers, procurement and quality assurance teams, and certification authorities.
- Practical applications: structural aircraft components, high‑strength forged fittings and parts where weight-critical, high-strength aluminium forgings are required and section sizes are limited to 200 mm. Use of EN 3872:2005 ensures repeatable material properties, traceability and compatibility with aerospace procurement and certification processes.
