Especially good for seawater corrosion resistance. Particularly suitable for the welding and hard facing of copper nickel such as machinery, desalting of seawater, ship-building, oil refinery, and food processing industries. Also suitable for welding of nonferrous alloys, dissimilar steel materials.
High strength and ductility
Low resistance temperature coefficient, wide operating temperature range (below 480℃)
Good weldability and processability
Stable arc, small splash, uniform slag covering, easy slag removal, good weld forming
