Overview

EN 2704:2015 (CEN) is an aerospace-series material standard that specifies requirements for aluminium alloy AL‑P2024 (AlCu4Mg1) in the T3511 condition, produced as drawn bars with a maximum external diameter De ≤ 75 mm. The standard defines chemical, metallurgical and mechanical requirements, delivery condition and inspection/testing methods for use in aerospace applications.

Key topics and requirements

• Material designation: AL‑P2024 - AlCu4Mg1, T3511 (solution treated and controlled stretched).
• Form and dimension: Drawn bars, diameter De ≤ 75 mm.
• Delivery condition (T3511): solution treated, controlled stretched by ~3% (minor straightening permitted), ambient temperature.
• Mechanical properties: proof stress Rp0.2 ≥ 315 MPa; tensile strength Rm ≥ 440 MPa; elongation A ≥ 13% (note: A50 mm ≥ 12% for De ≤ 10 mm as a specific note). Hardness (HBW) is given as informational.
• Electrical conductivity: specified range of approximately 17–20 MS/m (see EN 2004-1 for test method).
• Inspection for defects: external and internal defect acceptance and ultrasonic inspection requirements referenced to EN 4400-3 and EN 4050-4 (internal defects acceptance: Class 3).
• Testing and inspection: dimensional, marking, and test-piece rules follow EN 4400-3; test methods for conductivity and ultrasonic inspection are normatively referenced.
• Product qualification: qualification programme to be agreed between manufacturer and purchaser (per EN 4400-3).

Practical applications and users

• Intended for aerospace applications where high-strength wrought aluminium drawn bars in the 2024 family are required.
• Typical users include:
  • Aerospace material suppliers and mill producers offering AL‑P2024 drawn bars.
  • Procurement and quality assurance teams specifying material acceptance criteria.
  • Design and stress engineers selecting aluminium bar stock for structural components (using the stated mechanical property limits).
  • Test laboratories performing conductivity and ultrasonic inspections to the referenced EN methods.

Related standards (normative references)

• EN 4400-3 - Technical specification for aluminium bars and sections (delivery, inspection).
• EN 2004-1 - Test method: electrical conductivity of wrought aluminium alloys.
• EN 4050-4 - Ultrasonic inspection - acceptance criteria for bars/forgings.
• EN 4258 and EN 4500-2 - Series organization and drafting rules for aerospace metallic material standards.

EN 2704:2015 provides a concise, harmonized specification for AL‑P2024 T3511 drawn bars (De ≤ 75 mm) ensuring consistent production, testing and acceptance across the European aerospace supply chain. Keywords: EN 2704:2015, AL‑P2024, AlCu4Mg1, T3511, drawn bars, aerospace aluminium, De ≤ 75 mm.
