General Information
Overview
EN 3955:2001 (CEN) defines the requirements for the aerospace series silver base alloy AG-B12401 (AgCu40Zn5Ni) used as a filler metal for brazing in the form of rolled foil. This standard establishes expectations for material identity, form and suitability for aerospace brazing applications, supporting controlled manufacturing and reliable joint performance.
The document is intended for material producers, aerospace manufacturers, procurement teams and quality engineers who specify or use silver-based brazing foils in assemblies subject to aviation and space industry requirements.
Key Topics
- Material designation and identity: The standard covers the alloy designation AG-B12401 (AgCu40Zn5Ni) and confirms it as a silver-base filler metal for brazing.
- Form factor: Focuses on the rolled foil form, addressing the needs of processes that require thin, consistent brazing consumables.
- Aerospace suitability: Emphasizes the application domain, ensuring the filler metal meets requirements appropriate for aerospace use.
- Quality and conformance: Guidance for manufacturers and users on expectations for consistent production, documentation and control of the foil product.
These topics provide a framework for ensuring that AG-B12401 foil supplied or specified for brazing meets end-user needs for traceability and consistent manufacturing performance.
Applications
EN 3955:2001 is oriented to practical aerospace brazing uses where a silver-base filler metal in foil form is preferred. Typical application benefits include:
- Precision brazing where rolled foil enables controlled placement of brazing alloy in assemblies
- Repeatable joint quality through a standardized filler material and form
- Manufacturing control including procurement specification, acceptance testing and traceability in aerospace supply chains
The standard supports designers and process engineers in selecting the correct filler metal form (rolled foil) and in documenting material requirements for production and inspection.
