ALmitas+ MONOBRAZE(Filler-free brazing technology)
Share
Drastically enhancing recyclability and production eciency
Features
- Single-layer material
The materials are easy to recycle as filler metal is not used. - Joining with filler metal
Possible to join metals in a similar way to the method using filler metal. - Similar technique to brazing
Conventional brazing facilities can be used for this technique. - Similar properties as clad materials
The mechanical properties and corrosion resistance are equal or surpass those of common clad materials.
Comparison between MONOBRAZE fin and clad fin
- MONOBRAZE is a registered trademark of UACJ Corporation in Japan.
