Overview

EN 2390:2019 is a European standard developed by CEN that specifies the requirements for aluminium alloy 6082-T6 tubes used in aerospace structural applications. This standard targets tubes with wall thicknesses ranging from 0.6 mm to 12.5 mm, designed for the aerospace and defence industries. Aluminium alloy 6082-T6 is recognized for its excellent mechanical properties, corrosion resistance, and machinability, making it highly suitable for structural components in aircraft and related aerospace equipment. EN 2390:2019 is part of a series of metallic material standards for aerospace, ensuring consistency, safety, and performance across aerospace manufacturing.

Key Topics

• Material Specification: Defines the aluminium alloy 6082-T6 chemical composition limits including silicon, iron, manganese, magnesium, and others to ensure consistent mechanical and chemical properties.
• Dimensional Range: Covers tubes with wall thickness (a) between 0.6 mm and 12.5 mm, used for structural purposes.
• Delivery Condition: Tubes must be supplied in the T6 condition, involving solution heat treatment followed by artificial aging to achieve desired strength and durability.
• Mechanical Properties:
  • Proof stress (Rp0.2) of at least 240-255 MPa depending on tube thickness.
  • Tensile strength (Rm) of minimum 310 MPa for all thickness ranges.
  • Elongation requirements ensuring ductility with minimum elongation depending on thickness and test length.
• Testing Requirements: Includes tube flattening tests per EN 2002-10 to verify mechanical performance and dimensional integrity.
• Manufacturing Process: Primarily focuses on drawn tubes with specific references to EN 2070 and EN 2257 standards for aluminum alloy products and tube dimensions.
• Heat Treatment: Specifies the heating parameters and aging times required to achieve the T6 temper.

Applications

EN 2390:2019 aluminium 6082-T6 tubes are designed explicitly for aerospace structural applications, including:

• Aircraft Frame Components: Supporting structures where strength-to-weight ratio is critical.
• Aerospace Mechanical Systems: Tubular frameworks requiring high fatigue resistance and corrosion protection.
• Lightweight Aerospace Assemblies: Secondary structures and internal components benefiting from aluminium’s weight savings.
• Defence Equipment: Tubular elements for military aviation and aerospace defence technologies.

These tubes provide the mechanical reliability needed for safety-critical aerospace environments while facilitating ease of fabrication and long-term durability.

Related Standards

EN 2390:2019 is closely linked with other aerospace and aluminium standards to ensure comprehensive material quality control:

• EN 2070-1 & EN 2070-4: Technical specifications for aluminium and aluminium alloy wrought products, including tubes for structures.
• EN 2257: Circular tubes for structures with nominal diameters from 6 mm to 100 mm and thicknesses from 1 mm to 6 mm.
• EN 2002-10: Test methods specifically for aerospace series metallic materials, such as the tube flattening test.
• EN 4258: Describes the organizational framework and general approach for aerospace metallic materials standards.
• EN 4500-2: Provides rules for drafting and presenting aluminium and magnesium alloy standards, guiding the preparation of EN 2390.

Practical Value

Compliance with EN 2390:2019 assures aerospace manufacturers and suppliers of:

• Consistent Material Quality: Meeting strict chemical and mechanical property limits.
• Enhanced Safety and Performance: Standardized testing and heat treatments ensure structural reliability.
• Interoperability Within Aerospace Industry: Harmonization across European aerospace manufacturers and suppliers.
• Efficient Procurement: Reference to a recognized standard facilitates quality control and reduces specification disputes.
• Support for Innovation: Clear requirements enable material engineers to develop cost-effective, lightweight structural components.

By adhering to EN 2390:2019, companies enhance product safety, reduce costs associated with material failures, and align with aerospace industry best practices for aluminium alloy 6082-T6 tubes.
