INTERNATIONAL CLASSIFICATIONS

AWS/ASME A 5.15 E NiFe-CI

DIN 8573: E NiFe-1 BG13

ISO 1071: E NiFe NFA 81-342: E NiFe BG 13

FEATURES & APPLICATIONS

The high deposition rate of this electrode creates an extremely narrow heat affected zone. This feature is suitable for all weldable cast irons that require post weld machining.

  • One of a kind heavily copper clad “Tri-metal” cored cast iron electrode.
  • Visually unique core wire creates immediate customer interest.
  • High efficiency weld metal transfer totally eliminates electrode overheating.
  • Proprietary copper-nickel-iron deposit chemistry yields the ultimate combination of softness, ductility and tensile strength.
