Full title and description

Aerospace series — Heat resisting alloy CO-WH4102 (CoCr28W20Ni5V1) — Filler metal for welding — Wire and rod. Specifies designation, production and delivery requirements for the cobalt‑chromium‑tungsten‑nickel‑vanadium filler metal CO‑WH4102 in wire and rod form for aerospace welding and manufacture of pre‑forms.

Abstract

This standard sets out the requirements for the heat‑resisting filler metal CO‑WH4102 (CoCr28W20Ni5V1) supplied as wire or rod for aerospace applications. It covers material designation, permitted production and delivery conditions, and references product‑qualification and inspection procedures in related aerospace metallic‑materials standards.

• Publisher: European Committee for Standardization (CEN); implemented nationally (example: BSI as BS EN 4326:2001).
• ICS / categories: 49.025.15 — Non‑ferrous alloys in general (aerospace metallic materials classification).
• Edition / version: EN 4326:2001 (published 2001; national adoptions often published as 2002 editions).
• Number of pages: Varies by national publication and format (examples: BS EN listing shows 10 pages; some national adoptions display 6–9 pages depending on national foreword and formatting).

Scope

The standard applies to the heat‑resisting filler metal CO‑WH4102 (CoCr28W20Ni5V1) supplied as wire and rod for aerospace welding. Its scope covers requirements relevant to production, delivery condition (cast/extruded and where applicable annealed), and suitability for manufacture of pre‑forms; specific test programmes and product qualification are referenced to other EN aerospace material standards.

Key topics and requirements

• Material designation and chemical composition specification for CO‑WH4102 (CoCr28W20Ni5V1).
• Permitted product forms: wire and rod for welding and pre‑form manufacture.
• Production and melting method(s) (e.g., air‑melt routes) and acceptable manufacturing routes (cast, extruded).
• Delivery condition requirements (cast/extruded, annealed where applicable) and traceability expectations.
• Reference to qualification, inspection and test procedures (standard refers to related EN documents rather than repeating detailed test methods).

Typical use and users

Used by aerospace materials engineers, welding and repair shops for aircraft and aero‑engine components, filler‑metal manufacturers, procurement and quality managers specifying or accepting filler wire/rod for high‑temperature assemblies, and certification/inspection bodies involved in aerospace supply chains.

Related standards

This standard is part of the EN aerospace metallic‑materials series and cross‑references other EN documents for product qualification and test programmes (examples cited in the standard include EN 2043, EN 3879, EN 4258 and drafting guidance such as EN 4500‑3). Users should consult those referenced standards when specifying qualification and inspection arrangements.

FAQ

Q: What is this standard?

A: A European aerospace material standard (EN 4326:2001) that specifies requirements for the heat‑resisting filler metal CO‑WH4102 (CoCr28W20Ni5V1) supplied as wire and rod for welding and pre‑form manufacture.

Q: What does it cover?

A: Material designation, permitted forms (wire/rod), production and delivery conditions, and references to qualification/inspection procedures in related EN aerospace material standards; it does not repeat all test methods but points to the appropriate EN documents for qualification.

Q: Who typically uses it?

A: Aerospace manufacturers and repair organisations, filler‑metal producers, welding consumable suppliers, procurement and quality/inspection teams in the aerospace supply chain.

Q: Is it current or superseded?

A: EN 4326 was published in 2001 and implemented nationally (for example as BS EN 4326:2001). Several national bodies published their national editions in 2002. National implementations and editorial formats vary; users should check the relevant national standards body (for example BSI for the UK) for the current legal/active status in their jurisdiction.

Q: Is it part of a series?

A: Yes — it belongs to the EN aerospace metallic‑materials series and is linked to the general organisation of material standardization for aerospace (see EN 4258 and related EN documents for series structure and cross‑references).
