Overview
SIST EN 2046:2004 defines the dimensional and tolerance requirements for hexagonal bars that are drawn from aluminium and aluminium alloys, focusing on products designed for aerospace applications. This European standard covers hexagonal bars with a width across flats ranging from greater than 7 mm up to 50 mm, specifying tolerance class h11. By standardizing these key parameters, the document ensures consistency, interchangeability, and high performance of critical components used in aerospace manufacturing.
Key Topics
- Product Scope: Drawn hexagonal bars made from aluminium and its alloys, with width across flats 7 mm < a < 50 mm, intended for the aerospace sector.
- Tolerance Class h11: The standard establishes the dimensional tolerances in accordance with class h11, ensuring that all bars meet tight performance requirements, reduced variability, and fit seamlessly into assemblies.
- Dimensional Requirements:
- Width across flats: Offers precise measurement intervals for nominal sizes within the 7 mm to 50 mm range.
- Lengths: Bars may be supplied in fixed or random lengths, with specified minimum and maximum limits to comply with order specifics.
- Geometric Tolerances:
- Straightness and Twist: The standard references EN 3848 for measuring form deviations, including straightness and twist over the length of the bar.
- Corner Radii and Surface Flatness: Defines allowable corner radii for different widths and incorporates flatness within the width across flats tolerances for quality assurance.
Applications
The specified hexagonal bars are primarily used in aerospace manufacturing, where precision components are critical for safety and performance. Typical applications include:
- Structural elements and support parts in aircraft design
- Fasteners and coupling components benefiting from the mechanical properties of aluminium alloys
- Machined parts where consistent dimensions and surface integrity are essential
- Assemblies where interchangeability across suppliers and consistency in performance are crucial
By adhering to SIST EN 2046:2004, manufacturers demonstrate compliance with European and international aerospace quality systems, facilitating easier certification and acceptance across the supply chain.
