Overview
EN 4104:2001 (CEN / AECMA) defines the requirements for the aerospace nickel‑base brazing filler metal designated NI‑B40002, supplied in powder or paste form. The standard covers material designation, production method, delivery condition and the key quality and test requirements that apply to filler metals intended for brazing of aircraft and aerospace components.
Key topics and requirements
- Material designation and use: Nickel‑base brazing alloy NI‑B40002 - intended primarily for joining nickel and cobalt base heat‑resisting alloys.
- Forms and production:
- Supplied as powder or paste (paste = powder mixed with binder).
- Typical production: water or inert‑gas atomised and sieved powders; paste prepared by mixing atomised powder with an appropriate binder.
- Melting practice: air, inert gas or vacuum melted.
- Thermal properties:
- Solidus ~ 980 °C and liquidus ~ 1 065 °C (thermal analysis / differential thermal analysis specified).
- Quality & inspection (referenced tests and limits):
- Wettability (fusion test), thermal analysis, batch uniformity / material verification, particle size (sieve analysis), external defect inspection, marking and dimensional inspection - many checks are performed in accordance with EN 3875 (technical specification for filler metals for brazing).
- Metallic alloy content and other compositional requirements are specified for powder and paste forms.
- Delivery and documentation:
- Delivery condition is “as manufactured” (or mixed with binder for paste); delivery condition code UU.
- Product qualification and acceptance testing follow EN 2043 and the qualification programme is agreed between manufacturer and purchaser.
Applications and who uses this standard
- Primary applications: brazing and joining of high‑temperature nickel and cobalt‑base alloys in aerospace airframes, engines, and heat‑resistant assemblies.
- Users:
- Aerospace manufacturers and suppliers (design, production, procurement)
- Metallurgists and brazing process engineers
- Quality assurance / inspection teams and test laboratories
- Maintenance, repair and overhaul (MRO) organizations specifying approved filler metals
- Filler‑metal and powder suppliers aligning products with aerospace requirements
