Overview

SIST EN 3474:2005 is a European standard that specifies requirements for aluminium alloy AL-P2024-T81 in sheet and strip form with thicknesses ranging from 0.25 mm up to and including 6 mm, primarily intended for aerospace applications. Published by SIST, this standard harmonizes technical guidelines for the procurement, qualification, and acceptance of rolled aluminium alloy products within the aerospace industry.

The standard aligns with the broader series of European aerospace metallic materials standards, providing necessary coordination with other relevant documents such as EN 4258, EN 4400-2, and EN 4500-2.

Key Topics

• Scope and Material Designation
  Specifies aluminium alloy AL-P2024-T81 intended for aerospace use, available as sheet and strip between 0.25 mm and 6 mm in thickness.

• Delivery and Production
  Defines rolling production processes and pertinent delivery conditions (T81), including applicable heat treatment and cold work as outlined in related standards.

• Technical and Chemical Requirements
  References key chemical composition limits and technical specifications as detailed in EN 4400-2, supporting both suppliers and users in ensuring compliance.

• Physical and Mechanical Properties
  Includes parameters for proof stress, tensile strength, elongation, and hardness, validating material performance for demanding aerospace environments.

• Testing and Inspection
  Calls for uniform batch quality, strict dimensional inspection, and appropriate marking practices, ensuring product consistency and traceability.

Applications

The aluminium alloy AL-P2024-T81 covered by SIST EN 3474:2005 is particularly valued in the aerospace sector due to its high strength-to-weight ratio and favorable mechanical properties. Common applications include:

• Aerospace Structural Components
  Utilized for airframe skin panels, wing structures, and fuselage parts, where reliable strength and minimal weight are critical.

• Sheet and Strip Fabrication
  Employed in the manufacture of formed or stamped parts required for precision assemblies.

• General Aerospace Engineering
  Suitable for brackets, covers, and integrative elements in both civil and military aircraft construction.

The standardized requirements help manufacturers, purchasers, and engineers ensure material compatibility, safety, and performance in accordance with recognized international principles.
