Brazing using silver, copper and nickel based solders
Brazing is a process that meets the advanced challenges of joining metallic and non-metallic parts. In brazing, the components are joined by heating the filler metal above its melting point which then forms a joint as it solidifies. Soldering provides unique advantages over other joining methods, including:
- ability to join different combinations of materials (including metal to ceramic),
- combination of materials with limited microstructural evolution,
- forming joints of relatively high strength with high thermal and electrical conductivity.
Our group has extensive experience with vacuum brazing, such as silver, copper and nickel-based solders. We have also introduced brazing with ductile active solders (with titanium content) to join metals with brittle non-metallic materials. We have two vacuum furnaces with the technical parameters listed below.
As part of contractual research, we provide the following additional services:
- Leak detection of brazed components using the helium detector HLT 270 for joints.
- Destructive defectoscopy of performed joints
- Elemental analysis of EDX and SEM imaging in cooperation with Electron microscopy laboratories in ISI.
