A reliable and efficient method of joining together a wide range of metals, especially suited to joining precision foils 0.05mm thick and above.
A joining process in which the components are evenly heated to a temperature just over the melting point of the brazing alloy.
Gas Tungsten Arc Welding (GTAW) is frequently referred to as TIG welding. This is a commonly used high quality welding process.
Induction brazing is a well proven, controlled and localised form of brazing.
Deploying the latest manufacturing techniques to produce many different types of pressure sensitive elements.
Creative Group offer a wide range of inspection techniques to satisfy most quality requirements.
Creative Group offers a first-class precision machining service through its CNC machining and milling facility.
Vacuum brazing is a joining process in which the components to be joined are evenly heated overall to a temperature just over the melting point of the brazing alloy being used. The process is carried out in a vacuum, better than 1 x 10-3mbar.

There are a number of advantages and disadvantages associated with vacuum brazing and these are as follows.  

Advantages:

  • No surface oxidation or discolouration
  • Negligible distortion
  • No post cleaning operations required
  • Joins dissimilar materials
  • Flux free brazing
  • Repeatable quality
  • Simultaneous joints completed in one operation
  • Step brazing

Disadvantages:

  • Component size limitation dependent on size of vacuum chamber
  • All components heated to the same temperature during processing
  • Specialist skills are required

Typical braze alloys used are nickel, copper, gold or silver based. Brazing temperatures are typically between 750°C and 1200°C dependent on the braze alloy.

Our range of vacuum furnaces also enable us to carry out heat treatment to your specifications.
