Copper Clad Tri-Metal Non-Overheating Cast Iron

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.
