Overview

SIST EN 4900:2022 is a European Standard published by CEN that specifies the technical requirements for aluminium alloy 5086, H111 temper, in the form of extruded bars with diameters ranging from 10 mm to 300 mm. This standard is specifically designed for aerospace applications, ensuring consistent quality, mechanical properties, and dimensions suitable for critical aerospace components.

This standard forms part of the aerospace series of metallic material standards, which follow the general organization principles described in EN 4258. The SIST EN 4900:2022 standard serves manufacturers, suppliers, and quality control professionals involved with aluminium alloy 5086 products, harmonizing the technical specifications across member countries of the European Committee for Standardization.

Key Topics

• Material Specification
  Aluminium alloy 5086, known for its excellent corrosion resistance, high strength, and good weldability, is standardized in its H111 temper condition. The chemical composition limits are strictly defined to maintain consistent material performance.

• Form and Dimensions
  The document covers extruded bars with diameters between 10 mm and 300 mm, enabling usage in a variety of aerospace structural components. Bars must comply with dimensional tolerances as per EN 4400-3.

• Mechanical Properties

  • Proof stress: Minimum 110 MPa for bars ≤125 mm diameter, minimum 100 MPa for bars >125 mm up to 300 mm
  • Tensile strength: Minimum 250 MPa for bars ≤125 mm, minimum 230 MPa for larger bars
  • Elongation: Minimum 12% for both diameter categories
  • Hardness: Approximately 70 HB (for reference)

• Quality Assurance and Testing
  Visual inspection for surface imperfections (VT) and ultrasonic testing (UT) for internal defects are mandatory in compliance with EN 4400-3. Test pieces must be selected accordingly to validate mechanical properties and material consistency.

• Delivery Conditions
  Bars are delivered in the H111 heat treatment condition with a specified delivery code ‘U’. This ensures stable mechanical properties ideal for aerospace manufacturing processes.

• Standard Compliance and Implementation
  This standard must be adopted by national standardization bodies in CEN member countries, replacing any conflicting national regulations by November 2022.

Applications

SIST EN 4900:2022 aluminium alloy 5086 extruded bars are primarily used in aerospace manufacturing where high-performance, corrosion-resistant materials are crucial. Typical applications include:

• Structural components in aircraft and spacecraft
• Aerospace frames and supports requiring high strength-to-weight ratios
• Parts exposed to marine or humid environments due to alloy 5086's corrosion resistance
• Components where weldability and forming capability are essential

The standardization supports manufacturers and designers by providing reliable material specifications, promoting safe, efficient, and cost-effective aerospace production.

Related Standards

For comprehensive aerospace material management and specifications, SIST EN 4900:2022 is linked with the following standards:

• EN 4258: General organization of aerospace metallic materials standardization – outlines the series structure and classification
• EN 4400-3: Technical specification for aluminium alloy bars and sections – detailing technical and inspection requirements referenced within EN 4900
• EN 4500-2: Rules for drafting and presentation of standards for aluminium and magnesium alloys – guides terminology and documentation specifics for aerospace series

These related standards ensure harmonized procedures and quality benchmarks when dealing with aerospace aluminium alloys and their various forms.
