High temperature brazing

For this purpose, Ipsen offers manual, half- and fully-automatic single or multiple chamber furnaces.


Vacuum brazing systems – High temperature brazing under vacuum

High quality products from stainless steel, ceramic or aluminium may only – in accordance with today's technical requirements – be manufactured by brazing under vacuum. For this purpose, Ipsen offers manual, half- and fully-automatic single or multiple chamber furnaces. 

The advantages of vacuum brazing in Ipsen brazing systems

  • Adjustable furnace atmosphere
  • Excellent temperature uniformity
  • Fast temperature control
  • Environmentally friendly, flux-free brazing
  • No post-processing of parts, no disposal of flux residues, no wear of the furnace chamber by fluxes
  • Brazed joint does not affect the mechanical strength or corrosion resistance because of flux inclusions
  • High cleanliness brazed joint
  • High joint strength in the zone next to the base material 

The process Flux-free, high-temperature brazing under rough, medium or high vacuum is used for joints that will be subject to high thermal and mechanical loading. Generally, brazing alloys based on nickel, copper or noble metals in the form of crystalline foils, thin plating, powder or pastes are used.
