Oxygen-free copper alloy with alloyed elements such as silicon, tin and manganese suitable for GMAW and GTAW copper alloys welding. The alloyed elements improve the weldability without reducing the electrical conductivity. Phosphorus and silicon have a deoxidizer action.

Application: suitable for joining of copper and copper materials subject to high strain. Easily workable. In case of high thickness, it is recommended to preheat to 300 °C
