StarBlaze MIG NiFe
EN ISO 1071: NiFe
StarBlaze MIG NiFe is a high-performance solid MIG/MAG welding wire designed for welding cast iron and dissimilar joints. It features a Nickel-Iron (NiFe) based composition and is suitable for cold welding or minimal preheat welding (<300°C) of globular graphite iron (GJS), malleable iron (GJMB/GJMW), and cast iron to steel joints. This wire provides a machinable weld deposit and excellent compatibility with various cast iron types. Precision layer-wound and stable across short, spray, and pulsed arc applications.
- Diameters: 0.6 mm – 1.6 mm
