Overview
EN 3930:2001 specifies requirements for the aerospace nickel-base filler metal NI-B31001 (NiCr19Si10) supplied in powder or paste form for brazing. Prepared under the AECMA/CEN process, this material standard defines production methods, delivery condition and key quality attributes to support reliable brazed joints in high-temperature aerospace assemblies.
Key facts from the standard:
- Material designation: Nickel base braze alloy NI-B31001 (NiCr19Si10)
- Forms: Powder or paste (paste is powder mixed with binder)
- Production: Water or inert-gas atomised and sieved; melting by air, inert gas or vacuum methods
- Typical use: Joining nickel and cobalt base heat‑resisting alloys
Key Topics
The standard focuses on characteristics and verification criteria that ensure consistent performance of the brazing filler metal. Main topics include:
- Chemical composition and metallic content: The specification refers to alloy NiCr19Si10 and requires defined metallic alloy content for powder and paste forms.
- Particle size and sieve analysis: Particle size distribution is controlled by sieve analysis and inspected in accordance with referenced test methods.
- Wettability and fusion behaviour: Wettability (fusion tests) and thermal properties (solidus and liquidus temperatures) are specified or referenced to ensure predictable brazing behaviour.
- Batch uniformity and material verification: Requirements for batch verification and inspection are referenced to ensure consistency between deliveries.
- External defects and dimensional checks: Acceptance criteria for powders and pastes are aligned with the referenced filler-metal technical specification.
These topics are addressed primarily by referencing EN 3875 and related aerospace metallic material procedures rather than restating test protocols in full.
Applications
EN 3930 is intended for aerospace manufacturers, suppliers and quality engineers who specify or procure brazing filler metals for high-temperature assemblies. Typical applications include:
- Brazing of heat‑resistant nickel and cobalt alloys in turbine and engine components
- Repair and joining operations requiring controlled filler-metal chemistry and particle characteristics
- Production environments that use powder or paste brazing processes where reproducible wettability and fusion are critical
Adopting EN 3930 helps ensure material conformity, consistent joint quality and traceability for safety‑critical aerospace components.
Related Standards
This standard links to and references several aerospace materials standards and methods, including:
- EN 3875 - Filler metal for brazing – technical specification and tests
- EN 2043 - General requirements for semi‑finished product qualification
- EN 4258 - Organization of aerospace metallic material standardization
- EN 4500-6 - Rules for drafting material standards (specific rules for filler metals for brazing)
For procurement and qualification, EN 3930 advises that qualification programmes and delivery conditions be agreed between manufacturer and purchaser and executed in line with the referenced EN documents.
