Overview

EN 2369:2018 - Aerospace series: Wires, heat resisting alloys - Dimensions (0,2 mm ≤ D ≤ 8 mm) is a European Standard published by CEN that specifies the dimensional requirements and tolerances for heat‑resisting alloy wire used in aerospace construction. The standard defines preferred diameters, mass per unit length (based on a reference density), and diameter tolerances to ensure consistent geometry for manufacture, procurement and quality control of aerospace wire products.

Key topics

• Scope and range: Covers wire diameters from 0.2 mm to 8.0 mm, specifically for heat‑resisting alloys used in aerospace applications.
• Preferred diameters and mass: Lists preferred nominal diameters and associated cross‑sectional areas and masses (mass calculations use an average density of 8.1 g/cm³). This helps purchasers and designers specify standard sizes rather than bespoke diameters.
• Diameter tolerances: Specifies tolerance values that increase with nominal diameter. Tolerances range from approximately ±0.006 mm up to ±0.050 mm, depending on the wire diameter. These tolerances are provided in a table referenced in the standard.
• Designation format: Recommends how to designate wire in procurement/drawings, including elements such as material name, material standard number, dimensions (diameter, length or mass) and the dimension standard number.
• Conformance and technical specification: Wire supplied to EN 2369:2018 shall conform to the technical requirements of EN 4700‑004 (Aerospace series - Steel and heat resisting alloys - Wrought products - Part 004: Wire).

Applications

• Aerospace component manufacturers selecting heat‑resisting alloy wire for springs, fasteners, tension members, thermocouples, or high‑temperature assemblies.
• Design engineers and drawings teams who must specify standard wire sizes and tolerances to ensure interchangeability and manufacturability.
• Procurement and quality assurance teams verifying that supplied wire meets dimensional requirements and tolerance limits.
• Materials and process engineers coordinating with alloy material standards to ensure the correct grade and form factor for elevated‑temperature use.

Related standards

• EN 4700‑004 - referenced normative document for technical specification of wire (wrought products for steel and heat resisting alloys).
• Material‑specific standards that define chemical and mechanical properties of the heat‑resisting alloys used (these are cited within EN 2369:2018 as applicable).

EN 2369:2018 is essential when specifying, ordering or inspecting heat‑resisting alloy wire in aerospace contexts to ensure dimensional consistency, reliable fitment and compliance with European aerospace standardization.
