EN 2319:2018

Overview

EN 2319:2018 is a European Standard developed by CEN that specifies the requirements for aluminium alloy 2024-T3510 in drawn bar form with a maximum cross-section dimension (a) of 75 mm. This standard is part of the aerospace series for metallic materials and is tailored to meet the rigorous demands of aerospace applications. It sets the chemical composition, mechanical properties, heat treatment methods, and dimensional tolerances that ensure the high performance and reliability of aluminium alloy 2024-T3510 bars in the aerospace industry.

Key Topics

• Material Specification: Defines aluminium alloy 2024 with the T3510 temper condition, ensuring controlled solution treatment, water quenching, and natural aging for optimal mechanical characteristics.
• Chemical Composition: Sets limits on elements such as copper (3.8% to 4.9%), manganese (0.3% to 0.9%), magnesium (1.2% to 1.8%), chromium (max 0.1%), silicon, iron, nickel, zinc, titanium, zirconium, and others to maintain alloy purity and performance.
• Mechanical Properties: Includes requirements for proof stress, tensile strength, elongation, hardness, and electrical conductivity that align with aerospace application needs.
• Bar Dimensions and Tolerances: Covers drawn bars up to 75 mm in cross-section with dimensional tolerances as per EN 2044 to EN 2046.
• Heat Treatment: Focuses on T3510 condition involving solution treating at approximately 495°C ±5°C, followed by water quenching, stretching, and natural aging to achieve desired mechanical properties.
• Testing and Inspection: Specifies test methods based on related EN standards, including electrical conductivity testing (EN 2004-1), dimensional inspections, and marking protocols for traceability.
