Overview

SIST EN 3958:2002 is a European standard defining the specifications for the silver base alloy AG-B14001 (AgCu42Ni2) as a filler metal in brazing applications, specifically supplied in rolled foil form. This standard is part of the aerospace series developed by the European Committee for Standardization (CEN) to ensure high-quality metallic materials designed for aerospace manufacturing and repair.

Developed through collaboration within the aerospace industry and standardized by the European Association of Aerospace Manufacturers (AECMA), SIST EN 3958:2002 targets consistent production, testing, and material quality essential for critical aerospace components.

Key Topics

• Material Composition: The standard defines a precise chemical composition for the silver-based brazing alloy AG-B14001, including silver (Ag), copper (Cu), nickel (Ni), and minor allowable impurities.
• Form and Production: It specifies the alloy must be supplied as cold-rolled and cleaned foil, ensuring optimal mechanical and physical properties for brazing reliability.
• Mechanical Properties: EN 3958 outlines mechanical and thermal requirements including proof stress, tensile strength, elongation, hardness, shear strength, impact resistance, and heat treatment conditions.
• Testing and Inspection: The standard references other EN standards such as EN 3875 and EN 2043 for detailed material verification, dimensional and marking inspections, thermal analysis, and batch uniformity, ensuring consistent quality control.
• Scope of Use: Primarily intended for joining carbon steels, low alloy steels, and non-heat treatable austenitic steels in aerospace manufacture and repair.
• Heat Treatment and Delivery Conditions: Defines acceptance conditions for delivery either as-manufactured or annealed, with associated heat treatment requirements tailored for aerospace applications.
• Quality and Certification: Specifies qualification and product certification processes to be agreed upon between manufacturers and purchasers, reinforcing aerospace industry quality expectations.

Applications

The use of the AG-B14001 silver base alloy filler metal per SIST EN 3958:2002 is critical in aerospace brazing operations aiming for:

• High-Strength Joints: Joining diverse metallic components such as low alloy steels and austenitic stainless steels with reliable mechanical integrity under operational stress.
• Resistance to Harsh Environments: Aerospace components require brazed joints to withstand thermal cycling, vibration, and corrosion.
• Thickness Control: Rolled foil allows precise application thickness, essential for demanding aerospace manufacturing tolerances.
• Component Repair and Assembly: Used extensively in manufacturing lines and maintenance for aerospace structures and systems that rely on high-performance filler metals.
• Compatibility with Aerospace Alloys: Designed to meet aerospace manufacturing standards and integrate with related aerospace metallic materials.

Related Standards

SIST EN 3958:2002 works in conjunction with related European aerospace standards to ensure comprehensive coverage of material quality and process control:

• EN 2043 – Metallic materials: General requirements for semi-finished product qualification.
• EN 3875 – Metallic materials: Technical specifications for filler metals used in brazing.
• EN 4258 – General organization of standardization for aerospace metallic materials.
• EN 4500-6 – Rules for drafting and presentation specific to filler metals for brazing in aerospace.

These interlinked standards provide a cohesive framework supporting material selection, testing, qualification, and application procedures for aerospace manufacturers and suppliers.
