EN 573-3:2026/prA1

Overview

EN 573-3:2026/prA1 is a draft amendment to the European Standard that defines the chemical composition limits and forms of wrought aluminium and aluminium alloy products. Issued by CEN (European Committee for Standardization) and developed by CEN/TC 132, this standard ensures industry-wide consistency by aligning its chemical composition limits with those registered by the Aluminium Association in the United States. The document is vital for manufacturers, quality assurance professionals, and suppliers involved in the production or specification of aluminium products, as it addresses both material composition and categorized product forms.

Key Topics

• Chemical Composition Limits:
  The standard specifies precise chemical limits for both wrought aluminium and a broad range of aluminium alloys. This facilitates the selection and specification of materials for various industrial applications, ensuring reliability and global interoperability.

• Form of Wrought Products:
  Clear definitions for the forms in which aluminium alloys are produced - such as sheet, plate, foil, forgings, forgings stock, wire, drawn products, and extrusions - are detailed. This standardization allows for easier communication and product management across the aluminium supply chain.

• 5000 Series Aluminium Alloys:
  The amendment includes additional information regarding certain alloys (such as EN AW-5050A, building on EN AW-5050D), specifically focusing on the magnesium content and its implications for material processing and end-use.

Applications

EN 573-3:2026/prA1 is applicable across a wide range of industries and activities involving aluminium and aluminium alloys, including:

• Manufacturing and Fabrication:
  Ensures manufacturers select suitable alloy compositions for products like automotive components, aerospace parts, structural profiles, and packaging materials.

• Quality Control:
  Supports quality assurance personnel in verifying that the chemical composition of supplied materials fits international requirements, aiding in certifications and compliance.

• Procurement and Supply Chain Management:
  Provides buyers and logistics managers with reliable, harmonized specifications for ordering and inventory control of semi-finished aluminium products.

• Research and Development:
  Assists material scientists and engineers in designing new products and applications, ensuring compatibility with current industry standards and methodologies.

Related Standards
