Specification :

Oerlikon SUPERFONTE NiFe welding electrodes AWS SFA 5.15: E NiFeC1 Electrode having a nickel-iron core wire for welding cast iron without or with low preheating of up to +300oC. The weld metal features a low coefficient of thermal expansion and as a result, little shrinkage. It has higher strength properties than pure nickel weld metal and is therefore preferable used for welding nodular cast iron, white and black heart malleable cast iron, as well as austenitic nodular cast iron or joining these metals to components made of steel, copper or nickel materials. Easy arc striking and restriking, stable arc, smooth bead. Weld metal is machinable. Weld short beads.
