COPPERFIL CuSi3 is an S Cu 6560 / ER CuSi-A type solid MlG welding wire, supplied precision layer wound, depositing Cu-3Si weld metal. Suitable for use with inert shielding gases.
COPPERFIL CuSi3 is used for welding of copper base alloys, for example, copper-silicon, copper-zinc and galvanized sheets, also welded to steel. This wire is frequently used for joining in artistic foundries, for welding galvanized sheets and even as a steel cladding. It is also suitable for surfaces subject to corrosion.
