StarBlaze CI 55
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. Deposit is homogeneous, machinable and highly resistant against cracks. Provides porosity-free welding. Recommended for dissimilar welding of cast iron to steels and construction of cast iron. Ideal for repairing engine blocks, broken heavy castings, tool machine housings, gearboxes, reducing parts, and pump bodies.
