AUTOTHERME-CuNi

AWS: SFA 5.7 ERCuNi

Autotherme-CuNi is a solid wire for MIG welding, available in bright finish, gives smooth flow, stable arc and spatter free under optimum welding conditions. It is for joining and surfacing of wrought and cast alloys of similar composition as well as 80/20 and 90/10 alloys. Ideally suited for offshore applications because of its good resistance to the corrosion in seawater. It is also suitable for chemical process equipments, oil refineries, food industries, etc.
