Abraferro
Ferro-nickel electrode
Product description
Graphite-base coated electrode depositing a ferro-nickel alloy (60% Ni – 40% Fe) for the assembly and repair of spheroidal graphite cast irons or highly stressed irons.
Homogeneous deposit, highly resistant to cracking, particularly recommended for heterogeneous cast iron/steel assemblies or flanged cast iron assemblies. Good filler metal adhesion and spreading, as well as good resistance to hot cracking.
Applications:
Casting defects, repairs to engine blocks, machine tool frames, gearboxes, reduction gears, pump bodies, castings, valve bodies…

Heat input between passes as low as possible (max. 70°C) to minimize the risk of base metal cracking. Apply short beads of approx. 3 cm and hammer immediately before starting a new bead. Weld on clean, grease-free surfaces (grind joint beforehand).
