S321

The S321 soldering wire is a highly active soldering wire and a proven product for work in the metal, sheet metal and electrical industries. 

The S321 soldering wire contains urea as flux core and is also halogen-activated. Due to the high activity, the flux has good wetting characteristics on almost all metal surfaces (except aluminium).

application:
The S321 soldering wire can be used for manual and robot soldering and flame brazing. The low flux residues should be removed after the soldering process.
