Overview

EN 3965:2001 is a CEN/AECMA aerospace material standard that specifies requirements for the titanium-based brazing filler metal TI‑B17001 supplied as rolled foil. The standard covers material designation, production method, delivery condition and key test/inspection requirements for filler foil intended for brazing applications in the aerospace sector. EN 3965 is part of the EN metallic materials series for aerospace and is intended to ensure consistent quality and fitness for purpose when joining titanium alloys.

Key topics and requirements

• Material form and production
  • Form: rolled foil designed specifically as a filler metal for brazing.
  • Production: foil produced by colamination of Cu–Ni foils between two Ti foils (laminated construction).
  • Melting method: inert gas or vacuum melted to control purity.
• Composition and chemistry
  • Defined as a titanium‑base brazing alloy TI‑B17001 with Cu–Ni components and controlled impurity limits; exact composition values are specified in the standard.
• Delivery and heat treatment
  • Delivery condition: supplied as manufactured or annealed; delivery condition code U.
• Thermal and fusion properties
  • Thermal analysis (DTA): liquidus ~940 °C, solidus ~900 °C - important for brazing process windows.
  • Wettability: evaluated by a fusion (wettability) test per referenced methods.
• Inspection, testing and quality
  • External defects, dimensional, marking and batch uniformity inspections referenced to EN 3875.
  • Product qualification and semi‑finished product requirements referenced to EN 2043; qualification program agreed between manufacturer and purchaser.
  • Additional mechanical and metallurgical tests (shear, bending, etc.) identified or referenced where applicable.

Applications and users

• Primary application: joining and brazing of titanium alloys in aerospace components where a reliable, laminated titanium‑based filler foil is required.
• Who uses this standard
  • Aerospace materials engineers and design authorities specifying brazing consumables.
  • Filler‑metal manufacturers and metal foil suppliers producing TI‑B17001.
  • Quality assurance, procurement and acceptance inspectors in aerospace OEMs and subcontractors.
  • Process engineers developing brazing procedures and qualification programs.

Related standards

• EN 3875 - Filler metal for brazing: technical specification and test methods (used extensively by EN 3965)
• EN 2043 - General requirements for semi‑finished product qualification
• EN 4258 - Organization of aerospace material standards
• EN 4500‑6 - Rules for drafting filler metal material standards

EN 3965:2001 helps assure consistent performance of titanium brazing foil TI‑B17001, enabling controlled brazing processes and reliable joints in critical aerospace assemblies.
