Brazing Preforms
Solid flux-cored brazing rings, helixes and cuts. Brazing Preform Parts by Fontargen Brazing, discover our preforms for efficient brazing processes where exact and reprodusicble brazing results are mandatory.
Brazing with a ring or preform part ensures an accurate control over filler metal volume and improves the brazing process.
- Many HVAC+R and HVAC-Automotive manufacturers will use this technology (instead of manual feeding) in future, e.g. for flame brazing
- Preform parts are required to cover a high variety of shapes and become thus more and more challenging.
As a response to this demand, our new ring machine allows us to produce a multitude of ring types ensuring more efficiency while brazing and a higher quality of braze joints. Furthermore, it allows us to reach higher manufacturing speed and shortened delivery times.
Fontargen Brazing provides the following standard brazing alloys:
