Product description
3% Silicon alloyed copper wire electrode for GMA (MIG) welding of copper(Cu), Cu-Si (silicon bronze), Cu-Zn (brass) and as well as surfacing of unalloyed or medium alloyed steels or cast irons. Due to less Zn burn and corrosion resistant weld metal, suitable for joining of galvanized steels. Resulted Zn burn is less and weld metal is corrosion resistant in galvanized steels. For large workpieces e.g. thicknesses exceeding 5 mm, a preheat at about 250°C is recommended.
