ER CuSn6

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.
