Vacuum brazing systems – Aluminium 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

The process uses magnesium containing brazing alloy in the form of batch-plated strips. During flux-free brazing under high-vacuum, the aluminium oxide skin breaks – before the brazing alloy starts to flow – and finally removed by the vaporising magnesium. 

 Single chamber brazing systems

  •  Parts up to 1,600 x 7,800 x 2,400 mm (W x L x H)
  • Workpiece weights up to 30 t
  • Temperature uniformity better than ± 5 K
  • Working vacuum in the range of less than 10-5 mbar  Three chamber brazing systems
  • Throughput of up to 2,000 kg per hour
  • Working vacuum of the brazing chamber in the range of less than 10-6 mbar
  • Temperature uniformity of the brazing chamber ± 5 K
  • Pre-chamber designed for cleaning of parts (thermal degreasing)
