EN 3932:2001

Overview

EN 3932:2001 is a European standard developed by CEN that specifies the technical requirements for the nickel base alloy NI-B13001 (also known as NiP11) used as filler metal for brazing in aerospace applications. This standard focuses on the use of this alloy in the form of amorphous foil, which is valued for its high-performance properties in joining processes within the aerospace manufacturing sector. The document ensures consistent quality, performance, and safety for aerospace components joined using this specialized filler metal.

Key Topics

• Nickel Base Alloy NI-B13001 (NiP11)
  This standard covers the composition and characteristics of the Ni-B13001 alloy, a nickel-based filler metal specifically designed to meet the stringent demands of aerospace engineering. The alloy offers exceptional corrosion resistance, mechanical strength, and thermal stability essential for aerospace environments.

• Filler Metal for Brazing
  EN 3932:2001 defines requirements for brazing filler metals used in joining dissimilar and high-temperature resistant materials. The filler metal adheres well to aerospace-grade metals, providing reliable joints that maintain structural integrity under extreme conditions.

• Amorphous Foil Form
  The filler metal is supplied in an amorphous foil form that allows for even melting and uniform distribution during the brazing process. This form enhances the precision and quality of joints, reduces defects, and improves manufacturing efficiency.

Applications

EN 3932:2001 is primarily applied in the aerospace industry for:

• Aircraft Component Manufacturing
  Utilized in the assembly of critical components where high-strength, corrosion-resistant joints are vital for safety and performance, including turbine parts, engine components, and structural assemblies.

• Spacecraft Engineering
  Suitable for use in spacecraft manufacturing due to its ability to withstand harsh environmental conditions such as extreme temperatures and oxidizing atmospheres encountered during space missions.

• Maintenance and Repair
  The standard supports repair operations on aerospace parts by providing specifications for filler metals that restore mechanical properties and durability without compromising safety.
