Overview

EN 4327:2001 is a CEN/AECMA aerospace material standard that specifies requirements for the heat-resisting filler metal designated CO-WH1401 (CoCr26Ni11W8). The standard applies to filler metal for welding supplied as wire and rod intended for aerospace applications and was approved by CEN on 2 May 2001. It forms part of the EN metallic materials series for aerospace, organised under EN 4258.

Key supply and material points recorded in the standard include:

• Designation: CO-WH1401 (CoCr26Ni11W8) - nominally containing chromium, nickel and tungsten (26% Cr, 11% Ni, 8% W in the alloy designation).
• Form: Wire and rod.
• Method of production: Cold drawn.
• Method of melting: Air melted.
• Delivery condition: Cold drawn and annealed; use condition code U.

EN 4327:2001 focuses on material identification, manufacture, delivery condition and the contractual requirements needed to ensure consistent performance of welding filler metal in critical aerospace assemblies.

Key Topics

• Material designation and chemical basis: The standard identifies the alloy by its AECMA/CEN designation and lists constituent elements used for verification (C, Si, Mn, P, S, Cr, Ni, W, Fe).
• Manufacturing and form controls: Wire and rod production method (cold drawing) and melting practice (air melted) are specified as part of the quality baseline.
• Delivery and heat treatment: Delivery condition is defined as cold drawn and annealed; further heat treatment or use conditions are designated by a code (U).
• Inspection and qualification requirements: References to inspection for external and internal defects, dimensional checks and marking are made via related filler-metal standards.
• Contractual qualification: Product qualification and the qualification programme are to be agreed between manufacturer and purchaser.

Applications

EN 4327:2001 filler metal CO-WH1401 is intended for welding applications in aerospace where high-temperature resistance and reliable weld performance are required. Typical practical benefits include:

• Consistent weld metallurgy for high-temperature service parts.
• Traceability and supply control through defined production and delivery conditions.
• Buyer/supplier qualification framework that supports aerospace procurement and certification processes.

Related Standards

This standard incorporates or references other EN documents that define general requirements and test/specification methods for aerospace metallic materials and filler metals:

• EN 2043 - General requirements for semi-finished product qualification.
• EN 3879 - Filler metal for welding - Technical specification.
• EN 4258 - Organisation of aerospace metallic material standards.
• EN 4500-3 - Rules for drafting heat resisting alloy material standards (specific rules).

For product qualification and detailed testing requirements, EN 4327:2001 refers purchasers and manufacturers to EN 2043 and EN 3879; a qualification programme must be mutually agreed prior to supply. The standard provides a clear baseline for procurement, inspection and traceability of CO-WH1401 welding wire and rod in aerospace use.
