Overview
EN 2049:2001 - Aerospace series: Extruded channel section in aluminium alloys - Dimensions - is a European (CEN) standard that defines the physical form, recommended dimensions and dimensional tolerances for extruded U‑channel (channel) sections made from aluminium alloys intended for aerospace applications. It is part of the EN aerospace metallic materials series and establishes a common dimensional basis for manufacturers, designers and procurement in the aerospace supply chain.
Key topics
- Scope and form
- Specifies the form (U‑profile / extruded channel section) and range of recommended sizes and cross‑section shapes (see figure reference in the standard).
- Recommended dimensions and mass
- Provides a tabulated set of heights, widths, wall thicknesses and linear masses for standard channel sizes (heights in the published table range from small sections up to larger profiles-e.g., 15 mm to 250 mm).
- Linear mass values are given; calculated mass information in the document uses a density of 2.8 kg/dm3 for reference.
- Tolerances and geometric controls
- Dimensional and length tolerances as well as geometric tolerance rules are specified by reference to EN 2066 (Aerospace series – Extruded section in aluminium and aluminium alloys – General tolerances).
- Normative references and series context
- This standard is linked to the general organization of the aerospace metallic material standards described in EN 4258 and incorporates other normative references where applicable.
Practical applications
- Use EN 2049:2001 when specifying or procuring extruded aluminium U‑channels for aircraft structures, secondary structure, mounting rails, interior fittings, brackets and support members in aerospace systems.
- Useful for:
- Design engineers defining cross‑section geometry and selecting standard profiles.
- Extrusion manufacturers producing aerospace aluminium channel sections to ensure interchangeability.
- Quality inspectors and procurement teams verifying dimensions, mass and conformity to aerospace tolerances.
- Aerostructures suppliers and OEMs aligning product specifications across the supply chain.
Who should use it
- Aerospace component designers, structural engineers, extruders, supply chain/specification writers, manufacturing quality inspectors, and procurement specialists working with aluminium alloy extrusions for aerospace.
