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).
· Very high activation
· Suitable for most metal surfaces
· Residues must be removed
· Residues are easily soluble in water
· Not for stainless steel and aluminium
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.
