Cast Iron Electrodes
SUPERLINK MONEL
A nickel-copper (Monel-type) electrode designed for welding cast iron to copper-nickel alloys and for repair of cast iron where corrosion resistance to brine, seawater, and mild acids is required. Produces machinable deposits. Also used for joining cast iron to CuNi alloys.
Technical specifications
| Ni | Cu | Fe | Mn | Si |
|---|---|---|---|---|
| 60–70% | 25–35% | ≤2.5% | ≤2.0% | ≤1.0% |
| Tensile strength | ≥345 MPa |
|---|---|
| Hardness | ~130–170 HB |

Welding procedure & parameters
DC+ (DCEP) preferred. Short bead technique. Preheat 100°C–150°C. Keep interpass temperature low. Peen each bead.
Typical applications
Repair of cast iron components in marine, chemical, or brine-handling service. Joining cast iron to copper alloys or CuNi piping. Pump bodies and valve bodies in seawater service.
Storage & handling notes
Provides improved corrosion resistance over NiFe types in specific corrosive environments. Store in dry condition.
