Why ERNiFeCr-2?

Primarily for welding high strength aircraft components and liquid rocket components involving cryogenic temperaturesHigh heat input processes such as MIG welding often result in micro fissuring. This alloy can be age hardened to higher strengths.

ERNiFeCr-2 Application field:

Used for welding alloys 718, 706 and X-750.

Wire can be supplied in coils or straight lines and several different diameters are available as shown in the table below:
