Overview

EN 4326:2001 is a European aerospace material standard published by CEN and prepared by AECMA. It covers the heat-resisting filler metal alloy CO-WH4102 (CoCr28W20Ni5V1) in wire and rod forms for welding applications. The standard defines production and delivery conditions relevant to aerospace use and identifies this material as suitable for the manufacture of pre-forms.

Key administrative points:

• Published as a CEN standard and to be implemented as a national standard across CEN member countries.
• Developed within the EN metallic materials series for aerospace applications (see EN 4258 for series organization).

Key Topics

The standard concentrates on designation, production methods and delivery requirements rather than detailed mechanical property tables. Main points include:

• Material designation: Heat resisting alloy CO-WH4102 (CoCr28W20Ni5V1) - a cobalt-chromium-tungsten-nickel-vanadium alloy intended as filler metal for welding.
• Form: Supplied as wire and rod, optimized for welding processes and pre-form manufacture.
• Method of melting: Specified as air melted in the standard.
• Production methods: Cast or extruded production routes are referenced.
• Delivery condition: Supplied cast or extruded and annealed where applicable.
• Inspection and verification: References to tests and inspection requirements are made by cross-reference to other EN aerospace standards rather than repeating all test methods in this document.

Applications

EN 4326:2001 is targeted at aerospace welding and repair operations where heat-resisting filler metals are required. Practical applications include:

• Welding and joining of high-temperature components in aircraft and aerospace systems.
• Manufacture of pre-forms and filler components that require good heat resistance and compatibility with cobalt-chromium-based superalloys.
• Production and supply-chain specification for manufacturers, purchasers and quality managers who need standardized filler metal requirements for aerospace assemblies.

Benefits for users:

• Ensures consistent material designation and supply conditions for CO-WH4102 filler metal.
• Facilitates procurement and quality assurance by referencing harmonized EN requirements.
• Supports traceability and conformity for aerospace manufacturing and repair.

Related Standards

EN 4326:2001 references and works alongside several EN standards in the aerospace metallic materials series. Relevant linked standards include:

• EN 2043 - General requirements for semi-finished product qualification
• EN 3879 - Filler metal for welding - Technical specification
• EN 4258 - General organization of material standardization for aerospace
• EN 4500-3 - Specific drafting rules for heat resisting alloys

For product qualification and detailed test programmes, the standard indicates that qualification shall be agreed between manufacturer and purchaser and refers to EN 2043 and EN 3879 for specific procedures. For procurement or design, reference EN 4326 when specifying CO-WH4102 filler metal in wire or rod form for aerospace welding.
