VAcuum brazing

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.

Additional services

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
