Overview

EN 3887:2001 (Aerospace series) specifies the requirements for the heat‑resisting filler metal CO‑WH4101, designated CoCr20W15Ni, intended for welding in aerospace applications. Prepared by AECMA and published by CEN, the standard covers material designation, production and delivery conditions, and references for testing and qualification tailored to aerospace industry needs.

Key topics and requirements

• Material designation and nominal chemistry: The filler metal is identified as CO‑WH4101 (CoCr20W15Ni) - a cobalt‑based, heat‑resisting alloy with chromium and tungsten as major alloying elements and nickel present. The standard provides chemical composition limits and classification consistent with aerospace material practice.
• Form and manufacture: Specifies permitted product forms - filler wire and filler rods - and production methods such as cold drawing for final form and consumable‑electrode remelting as the melting route.
• Delivery condition: Typical delivery state is cold drawn and annealed; the standard uses a delivery‑condition code (U) to indicate use condition requirements.
• Inspection and quality: Refers to EN 3879 for inspection criteria covering external defects, residual and internal defects, batch uniformity (material verification), marking and dimensional inspection. Product qualification is governed by EN 2043 and a qualification programme to be agreed between manufacturer and purchaser.
• Testing references: Normative references include EN 3879 (filler metals for welding), EN 2043 (semi‑finished product qualification), EN 4258 (standard organization), and EN 4500‑3 (drafting rules for heat‑resisting alloys).

Applications

• Aerospace welding and repair: Welding of high‑temperature components where corrosion/oxidation resistance and high‑temperature strength are required (e.g., gas turbine parts, combustion liners, heat‑exposed structural components).
• Fabrication of heat‑resistant assemblies: Joining cobalt‑based superalloy components or cladding operations requiring compatible filler metals.
• Procurement and specification: Used by engineers and procurement specialists to specify compliant filler material for aerospace manufacturing, overhaul, and maintenance.

Who should use this standard

• Aerospace materials engineers and welding engineers
• OEMs and subcontractors producing or repairing high‑temperature components
• Quality, inspection and procurement professionals specifying filler metal requirements
• Test laboratories performing material and conformity testing for aerospace suppliers
