SIST EN 2511:2005

Overview

SIST EN 2511:2005 is a European standard developed by CEN covering Aerospace series aluminium alloy AL-P7075-T7351 plates with thicknesses between 6 mm and 100 mm. This standard defines stringent requirements for the chemical composition, mechanical properties, production methods, and quality controls specifically tailored for aerospace applications. It ensures uniformity and reliability in aluminium alloy plates used in critical aerospace structures, supporting high performance and safety standards in the aerospace industry.

The standard is part of a broader series of metallic material standards for aerospace applications, designed in line with EN 4258 and drafted following EN 4500-2 guidelines. SIST EN 2511:2005 has been adopted by national standards bodies across Europe, ensuring harmonized specifications for manufacturers and users of AL-P7075-T7351 aluminium alloy plates.

Key Topics

• Material Specification:
  Focuses on aluminium alloy AL-P7075-T7351, a high-strength alloy widely used in aerospace for its excellent mechanical properties and corrosion resistance.

• Plate Thickness Range:
  Applies to plates with thickness greater than 6 mm and up to 100 mm, aligning with typical aerospace structural component requirements.

• Chemical Composition:
  Specifies limits for key elements such as Silicon (Si), Iron (Fe), Copper (Cu), Magnesium (Mg), Chromium (Cr), Zinc (Zn), and Titanium (Ti) to guarantee alloy consistency.

• Mechanical Properties:
  Defines minimum levels for proof stress (Rp0.2), tensile strength (Rm), elongation (A), and other properties at ambient temperature. These values ensure the material meets durability and strength standards required for aerospace engineering.

• Heat Treatment and Delivery Conditions:
  Details the T7351 temper designation including solution heat treatment, quenching, controlled stretching, and artificial aging. These treatments optimize strength and stress corrosion resistance.

• Testing and Quality Control:
  Followed according to EN 4400-1, encompassing dimensional inspections, mechanical and corrosion testing, and batch uniformity. This guarantees high-quality production and traceability.

• Applications Orientation:
  Made to meet aerospace requirements, such as resistance to stress corrosion and external/internal defect tolerances.

Applications

The SIST EN 2511:2005 standard is instrumental for aerospace manufacturers and suppliers involved in producing and certifying aluminium alloy plates for:

• Aircraft Structural Components
  Wing spars, fuselage frames, and other load-bearing aerospace parts requiring high strength-to-weight ratios.

• Aircraft Engine Parts
  Components exposed to cyclic stresses and elevated temperatures.

• Aerospace Assemblies
  Where plate thickness and mechanical reliability conform precisely to strict aerospace design parameters.

• High-Performance Aerospace Materials Supply
  Enables manufacturers and purchasers to ensure material compliance and uniformity across international aerospace supply chains.

Adhering to SIST EN 2511:2005 helps aerospace companies improve product safety, reduce material failure risk, and maintain compliance with internationally recognized aerospace material standards.
