Overview

SIST EN 4215:2005 is a European Standard specifying requirements for aluminium alloy AL-P7175-T651 plates intended for aerospace applications. This standard covers plates with thickness greater than 6 mm and up to 80 mm. It is part of the aerospace series of metallic materials standards, developed under the guidance of the European Association of Aerospace Manufacturers (AECMA-STAN) and adopted by the European Committee for Standardization (CEN).

This standard defines the chemical composition, mechanical properties, delivery conditions, and quality controls for AL-P7175-T651 aluminium alloy plates, ensuring high performance and reliability in demanding aerospace environments.

Key Topics

• Material Specification

  • Aluminium alloy designation: AL-P7175-T651
  • Thickness range: > 6 mm to ≤ 80 mm
  • Production: Rolled plates
  • Heat treatment: Solution heat treated, water quenched, and artificially aged (T651 temper)

• Chemical Composition

  • Key elements include Zinc (5.1% min, 6.1% max), Magnesium (2.1% min, 2.9% max), and Copper (1.2% min, 2.0% max)
  • Controlled limits for Silicon, Iron, Manganese, Chromium, Titanium, and Aluminium base

• Mechanical Properties
  Different thickness ranges have specific minimum mechanical property requirements:

  • Proof stress (Rp0.2): ≥ 400 - 470 MPa depending on thickness and direction
  • Tensile strength (Rm): Minimum 490 - 540 MPa
  • Elongation at break: Minimum 2% to 8% according to thickness
  • Hardness, bending, shear strength, and impact strength tested as per EN 4400-1

• Testing and Inspection

  • Includes external and internal defect checks in accordance with EN 4400-1
  • Dimensional and marking inspections mandatory
  • Batch uniformity and product qualification to be agreed between manufacturer and purchaser

Applications

SIST EN 4215:2005 aluminium alloy AL-P7175-T651 plates are critical materials for the aerospace industry, offering exceptional strength-to-weight ratio and corrosion resistance. Typical applications include:

• Structural components of aircraft and aerospace vehicles
• High-strength machined parts for airframes and wing assemblies
• Aerospace manufacturing requiring plates of varied thickness with certified mechanical performance
• Environments demanding high fatigue resistance and dimensional stability under operational stresses

Related Standards

SIST EN 4215:2005 is closely linked to several key standards in the aerospace materials domain including:

• EN 4258 – General organization of aerospace metallic materials and standardization framework
• EN 4400-1 – Technical specification for aluminium and aluminium alloy wrought products, including plates
• EN 4500-2 – Rules for drafting and presentation of material standards focusing on aluminium alloys

These interrelated standards collectively ensure comprehensive quality control, material traceability, and performance criteria essential for aerospace manufacturing and certification.
