FONTA FN Ni

International Standards:
AWS SFA 5.15 : E Ni-C1
DIN 8573        : E Ni BG 22

Application & Properties:
FONTA FN Ni is recommended for all-position welding of thin cast iron sections where maximum machinability is required. Since the core wire is approximately 97% nickel, weld deposits are basically “soft” and can be shaped, milled, drilled, or tapped, while the color will match that of cast iron. FONTA FN Ni is specifically suited for repairing cracked or porous castings and to weld cast iron to itself or dissimilar metals such as low alloy and carbon steels.

FONTA FN NiFe

International Standards:
AWS SFA 5.15 : E NiFe-C1
DIN 8573        : E NiFe-1 BG 22

Application & Properties:
FONTA FN NiFe is designed for all-position joining and surfacing of cast iron, malleable iron and ductile iron to itself or dissimilar metals such as mild steels, stainless steel, wrought alloys or high nickel alloys. A core wire chemistry of approximately 55% nickel and 45% iron produces weld deposits with much lower weld shrinkage stress which in turn reduces the possibility of weld or heat-affected zone cracking. FONTA FN NiFe produces high strength, ductile weld deposits even when welding low grade cast iron containing excessive levels of phosphorus or other contaminants.

FONTA FN NiCu

International Standards:
AWS SFA 5.15 : E NiCu-B
DIN 8573        : E NiCu BG 22

Application & Properties:
FONTA FN NiCu is basic-graphite special coated electrode with a NiCu-alloyed core wire. This electrode is particularly suitable for safe cold welding of grey cast iron, cast steel and malleable cast iron. The colour of the weld deposit is very similar to cast iron. Therefore, The electrode is primarily suitable for repairing casting or machining defects on new castings.
