Overview

EN 3963:2001 (CEN / AECMA) defines the material requirements for Copper CU-BU9001 used as a filler metal for brazing in aerospace applications. The standard covers the product form (rolled foil), permitted manufacturing routes and key material attributes needed to support reliable joining in airframe and engine assemblies. It is part of the EN aerospace metallic materials series and references general qualification and test procedures from the EN/AECMA suite of standards.

Key Topics

• Material designation and composition: The standard identifies the material as Copper CU-BU9001 with a very high copper content (minimum Cu ~99.92%) and tightly limited impurities. Specific impurity controls and verification are part of the requirements.
• Melting method: Material is to be produced by inert gas or vacuum melting to ensure low contamination and consistent alloy chemistry.
• Form and manufacture: The product form is rolled foil, produced by cold rolling and cleaning. Delivery may be as-manufactured or annealed depending on purchaser agreement.
• Thermal properties: Thermal analysis (differential thermal analysis) is referenced; the standard notes the eutectic at about 1 083 °C and the requirement for fusion/wettability testing per EN 3875.
• Specification linkage: Many detailed tests, inspections and acceptance criteria are referenced to EN 3875 and EN 2043. Batch uniformity, dimensional checks and marking follow the referenced procedures.

Applications

• Aerospace brazing: Rolled-foil filler metal for joining components in aircraft and space systems where a high-purity copper filler is required.
• Joining ferrous and nickel-base alloys: The standard identifies typical use for joining ferrous alloys and some nickel-base alloys, where consistent melting behavior and wetting characteristics are critical.
• Manufacturing and repair: Useful for OEM manufacturing, repair shops and suppliers specifying brazing consumables for structural and subsystem assemblies.

Practical value: specifying EN 3963:2001 in procurement ensures consistent alloy chemistry, controlled melting behavior from inert/vacuum melting, and a common test/acceptance framework that aligns with aerospace qualification expectations.

Related Standards

• EN 3875 - Aerospace series: Filler metal for brazing - Technical specification (referenced for tests and acceptance)
• EN 2043 - Metallic materials: General requirements for semi-finished product qualification
• EN 4258 - Organization of aerospace metallic material standards
• EN 4500-6 - Rules for drafting filler-metal standards

For purchasers and designers, EN 3963:2001 should be used together with EN 3875 and EN 2043 to define qualification, batch verification and inspection criteria when specifying Copper CU-BU9001 rolled-foil brazing filler for aerospace use.
