Overview

EN 3342:2005 is a CEN (Aerospace series) standard that defines requirements for aluminium alloy AL‑P6061 in the T4 or T42 tempers, supplied as drawn or extruded bar and section with cross‑sectional dimension a or diameter D ≤ 150 mm. It is intended specifically for aerospace applications and sets delivery conditions, mechanical property minima and inspection/qualification references.

Key topics and requirements

• Material designation: Aluminium alloy AL‑P6061, temper T4 or T42.
• Form and size: Drawn or extruded bar and section, maximum a or D ≤ 150 mm. Orders must state whether product is extruded or drawn.
• Heat treatment / delivery conditions: Solution heat treatment and quenching followed by ageing are specified in the standard (e.g., solution 520–540 °C, quench to ≤ 40 °C and subsequent ageing/natural ageing as required for T4/T42) - refer to the full text for exact treatment wording and delivery codes (F, O, T4, T42).
• Mechanical property minima (representative values in the standard):
  • Proof stress R_p0.2 ≥ 110 MPa
  • Tensile strength R_m ≥ 210 MPa
  • Elongation A ≥ 14% (A or A50 mm)
• Inspection and testing: Dimensions, marking and inspection rules refer to EN 4400‑3 (Bar and section technical specification). Test pieces and sampling are also defined by EN 4400‑3.
• Quality / qualification: Product qualification program to be agreed between manufacturer and purchaser; batch uniformity, internal/external defect criteria follow EN 4400‑3.

Applications and who uses it

• Aerospace OEMs and suppliers specifying raw wrought aluminium bar and profile material for structural components, fittings and machined parts.
• Procurement and quality managers who need standardized purchase specifications and acceptance criteria for AL‑P6061 bars and sections.
• Design and materials engineers selecting alloy temper and form for machinability, strength and corrosion performance in aircraft applications.
• Material testing and inspection laboratories carrying out acceptance testing per EN 4400‑3 references.

Related standards
