SIST EN 2045:2004 - Aerospace series - Square bars, drawn in aluminium and aluminium alloys - Tolerance class h 11 - Thickness 6 mm < a < 50 mm - Dimensions

Overview

EN 2045:2001 (CEN / AECMA) defines the dimensional and tolerance requirements for drawn square bars in aluminium and aluminium alloys intended for aerospace use. It covers bars with a nominal thickness a in the range 6 mm < a < 50 mm, and applies tolerance class h 11. The standard is part of the aerospace metallic-materials series and is intended to ensure interchangeability, quality and consistent geometrical characteristics for aerospace components.

Key topics and technical requirements

  • Scope
    • Drawn square bars in aluminium and aluminium alloys for aerospace applications.
    • Thickness range: 6 mm < a < 50 mm.
    • Tolerance class: h 11.
  • Dimensions and recommended data
    • Recommended nominal sizes and linear mass values are provided (mass values calculated using a reference density of 2.8 kg/dm³).
  • Length and ordering
    • Orders must specify whether bars are supplied in fixed or random lengths. For random-length supply, the minimum and maximum lengths must be specified.
  • Corner radii
    • Recommended corner radii are listed by thickness band (examples from the standard):
      • 6–10 mm: r ≈ 0.5 mm
      • 10–30 mm: r ≈ 0.8 mm
      • 30–50 mm: r ≈ 1.0 mm
  • Tolerances
    • Dimensional tolerances: thickness tolerances follow h 11 for the specified thickness range.
    • Geometric tolerances: straightness, squareness, twist and surface flatness requirements are specified; measurement methods and symbols refer to EN 3848.
    • Surface flatness tolerance is included within the thickness tolerance.
  • Measurement methods
    • Geometric measurement methods and symbols are referenced to EN 3848; the standard also links to the general organization of aerospace metallic-material standards in EN 4258.

Practical applications

  • Ensures consistent, specifiable square-aluminium bar stock for:
    • Structural components, brackets and fittings
    • Machined parts and precision assemblies
    • Prototyping and production where aerospace-grade tolerances are required
  • Useful when traceable, reproducible dimensional quality is required across suppliers and national borders.

Who should use this standard

  • Aerospace manufacturers, OEMs and tier suppliers
  • Material and metal stock distributors
  • Design and mechanical engineers specifying raw material
  • Purchasing agents and quality inspectors verifying incoming stock
