Classification

| EN ISO class | E C NiFe CI 1 |
| Other standards | EN ISO 1071: E C NiFe CI 1 |
Purpose
- Nickel-iron cored stick electrode (AWS E NiFe-CI, EN ISO E C NiFe CI 1) — joining grey and malleable cast iron, and joining cast iron to hard-to-weld steels.
Why it works
The iron added to the nickel raises the deposit's mechanical strength versus FON Ni, at the cost of a somewhat harder heat-affected zone — chosen when the joint must carry more load than pure nickel allows, especially joining cast iron to hard-to-weld steel.
Fields of application
- Joining grey and malleable cast iron.
- Joining cast iron to hard-to-weld steels or cast parts.

Equivalence refers to the classification (AWS / EN ISO), not to product identity. In applications with a qualified procedure (WPS), validate the substitution before use.
Advantages
- Higher mechanical strength than FON Ni — the better choice when the joint must carry more load.
- Suited to joining cast iron with hard-to-weld steels.
Limitations
- Requires specific technique: short beads and gently peening each pass with a hammer while still hot — skipping this greatly increases cracking risk.
- Less machinable deposit with a harder heat-affected zone than FON Ni — if maximum crack tolerance is the priority, FON Ni is the better choice.
