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.
