StarBlaze CI 50
Ferro Nickel Electrode
Classification
AWS A 5.15: E NiFe-CI | DIN 8573: E NiFe-1 BG11 | ISO 7071: NiFe 1
Description and Applications
Graphite basic coated Ferro-Nickel alloy electrode for joining and repairing nodular cast iron. Produces a homogeneous, machinable, porosity-free deposit with high crack resistance. Recommended for dissimilar welding of cast iron to steels and for cast iron constructions. Applications include engine blocks, broken heavy castings, houses of tool machines, gearboxes, reducing parts, and pump bodies.
