Tin alloyed copper wire electrode for GMA (MIG) welding of copper and low alloyed copper alloys. Particularly used in electric and heat conductor parts, which are made of pure copper. Suitable for welding oxygen-free copper and copper materials subject to high strain. Gives pore-free and easily machinable welding seams.
6% Tin alloyed copper wire electrode for GMA (MIG) welding and surfacing of Cu-Sn (4 - 8 % Sn ; bronze), Cu-Zn (brass), and Cu-Sn-Zn-Pb alloys. Suitable for joining of copper alloys to steels, repair welding of cast bronzes and cladding on cast iron and steels. For large workpieces; e.g. thicknesses exceeding 5 mm, a preheat at about 250°C is recommended.
8% Aluminium alloyed copper wire electrode for GMA (MIG) welding of copper-aluminyum (Cu-Al) alloys (aluminium-bronzes). Also suitable for surfacing of parts subjected to metal to metal wear under high compressive stresses or in the presence of corrosive agents (acids, sea water).
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.
