BS EN 3930-2001 PDF

Full title and description

BS EN 3930:2001 — Aerospace series. Nickel base alloy NI-B31001 (NiCr19Si10). Filler metal for brazing — Powder or paste. This British adoption of the European standard specifies the designation and requirements for a nickel‑base brazing filler metal supplied in powder or paste form intended for aerospace applications.

Abstract

Sets out chemical designation, compositional requirements and the form (powder or paste) and related requirements for the nickel‑base filler metal NI‑B31001 (NiCr19Si10) used for brazing in aerospace manufacture and repair. The standard is part of the CEN aerospace series of material specifications.

Scope

Specifies the requirements for the nickel base alloy filler metal NI‑B31001 (chemical shorthand NiCr19Si10) supplied in the form of powder or paste for brazing operations in aerospace applications. The scope covers designation, compositional requirements, general product description and the requirements necessary to ensure material suitability for use in aerospace brazing processes. It is written as part of the CEN aerospace series and intended to be adopted by national standards bodies (hence the BS EN designation).

Key topics and requirements

• Designation and identification of the filler metal as NI‑B31001 (NiCr19Si10).
• Compositional limits and chemical requirements for the nickel‑base alloy (control of major alloying elements such as Cr and Si).
• Permitted product forms: powder and paste (requirements for form, consistency and suitability for brazing).
• Marking, packaging and identification requirements to ensure traceability for aerospace supply chains.
• Reference to applicable test methods, acceptance criteria and quality control required for aerospace use (as per aerospace series conventions).

Typical use and users

Used by aerospace material suppliers, brazing consumable manufacturers, aerospace OEMs and subcontractors, metallurgists, inspection and quality engineers, and procurement teams specifying filler metals for aircraft manufacture and repair. It is applied where a controlled nickel‑base brazing filler with the NI‑B31001 designation is required.

Related standards

Related items include other EN/CEN aerospace series standards covering filler metals, brazing processes and nickel‑base alloy specifications and the national adoptions of EN 3930 (e.g., DIN EN 3930, NEN‑EN 3930). Users should also consult applicable test method standards and other aerospace material specifications in the EN series.
