QuNi41 Bobbin – Laser Welding Wire Cast Iron NiFe – GJS / GGG & Grey Iron (EN ISO 1071 S C NiFe)
QuNi41 is a NiFe filler metal (approx. 59 % nickel, balance iron) for welding and repairing cast iron — to EN ISO 1071: S C NiFe (material ~2.4560). It suits ferritic and austenitic ductile cast iron (GJS / GGG, nodular iron) as well as build-up welding on grey iron (GJL / GG). Decisive in practice: the weld metal is work-hardening, machinable, polishable and chrome-platable — the repaired area can be finished just like the base material.
Recommended base materials
- GJS (GGG) — ductile / nodular cast iron, ferritic and austenitic
- GJL (GG) — grey cast iron (build-up welding)
- Other common cast iron grades
- Dissimilar joints with unalloyed and high-alloy steel, copper and nickel alloys
Typical applications
- Tool and mould repair — finishing by machining, polishing and chrome plating possible
- GGG valves and pump housings — repair of cast components
- Build-up and joining welds on ductile cast iron (GJS/GGG)
- Build-up welding on grey iron grades (GJL/GG)
- Dissimilar joints cast iron ↔ steel, copper, nickel alloys
- Corrosion-resistant cladding
Properties and advantages
- Finishable: work-hardening, machinable, polishable, chrome-platable
- NiFe weld metal absorbs carbon from the cast iron without becoming brittle
- Suitable for ferritic and austenitic nodular iron
- Also for dissimilar joints to steel, copper and nickel alloys
- Mechanical properties (pure weld metal, 20 °C): Re 300 MPa | Rm 500 MPa
