Why should you use BS EN 3875-Aerospace series: Filler metal for brazing?
When alternative attachment or joining methods, such as riveting, fasteners, or welding, are not possible, brazing is utilised to bring discrete components together. A filler metal with a substantially lower melting point than the base metals is employed to avoid high temperatures that would harm the parts themselves. Silver, copper, silver-copper alloys, and aluminium are commonly used in the aerospace industry for brazing.
BS EN 3875 provides users guidance on chemical composition, method of melting, form, method of production, limit dimension, delivery condition and more that facilitates transportation condition, storage and usability in aerospace applications.
BS EN 3875 provides users guidance on technical requirements, including general conditions, qualification requirements, release tests, retests, rejection, special tests, capability clause, statistical process control and more that ensure the properties of filler metal to meet the desired performance characteristics.
Guidance in BS EN 3875 allows users to assess and develop filler metal for brazing, which facilitates producing joints with minimal thermal distortion and residual stresses in aerospace applications.
