Vacuum brazing involves the joining of parent materials, below their melting point, by using a molten filler metal in a clean vacuum environment.
Process benefits include:
- Consistency – The furnace environment and process are automated, temperatures can be limited to avoid damage to sensitive microstructures in parent materials.
- Low distortion – The uniform heating of the whole assembly to relatively low temperatures causes lower stress than welding for example.
- Versatility – There is a vast catalogue of filler metals which can be used for different temperature ranges, parent materials (even non-metallics), and end-use environments.
- Low unit costs – Batch production in a single furnace cycle reduces unit price of components.
Successful brazement design depends upon:
- Joint geometry, capillary gaps and surface finish
- Choice of braze filler material (BFM)
- Planning for furnace tooling
Please contact the experienced staff at STG at the earliest stage of design to get the best end results.
STG develop novel brazed solutions for fusion challenges, but also supply components to medical, oil & gas, and cryogenics customers.
Vacuum brazed components made by STG are used in MRI machines across world. As part of this and similar work, STG develop robust processes for new products and bridge the gap from development to production to enable high-value supply chains.
