Vacuum Brazing

Vacuum Brazing

High-temperature brazing in a vacuum paves the way for versatile material combinations. This is achieved in a highly economical way.

Top performance with material combinations

Combining the thermal conductivity of copper, the corrosion resistance of stainless steel and other properties in one component? No problem with vacuum brazing!

As one of the leading suppliers in vacuum brazing technology, we join a wide variety of materials – primarily copper and stainless steel – but also other materials. The produced material joints are vacuum-tight, mechanically highly resilient, oxidation-free, absolutely clean and free of any solder residues. The capillary action ensures an optimum soldered seam – even in hard-to-reach places. This creates strong compounds that are characterised by very high strength and corrosion resistance.

  • Material-locking and mechanically highly resilient connections
  • Vacuum-tight joining of complex geometries
  • Secure material connections up to a material thickness of 0.1 mm
  • Soldering even of hard-to-reach areas thanks to capillary action
  • Flux-free joining and heat treatment in one work step
  • Flat connections up to a dimension of 500 x 500 mm

In our specially developed and electrically heated vacuum furnaces, we use the vacuum to prevent the oxidation that starts during heating. In addition, by using gases such as nitrogen or argon, we can create special ambient atmospheres that offer many different advantages.
