NiFe - CI
Application / Properties:
Electrode having a pure
nickel core wire, designed
for the welding of cast iron
without or with low preheat
(up to 300 C max). The weld
metal has a low coefficient
thermal expansion and
therefore little shrinkage.
It feature higher strength
properties than pure nickel
weld metal and
therefore preferred for
joining nodular cast iron,
white and black heart
malleable cat iron and
austenitic nodular cast iron
or for joining these
materials to components made
of steel, copper and nickel
materials. Easy arc
striking, stable arc, finely
ripped bead surface, weld
metal is machinable. Weld
short beads.
