Properties Magna 777 New Electrode for All Types of Cast Iron

Magna 777 New Electrode for All Types of Cast Iron is a widely used and high-quality welding electrode, specifically developed for welding all types of cast iron, even in difficult or critical situations.

Very high crack resistance: The specially alloyed nickel-iron core absorbs stresses and prevents shrinkage cracks, even on difficult or contaminated castings.
Perfect adhesion: Adhesion remains reliable even on aged, rusty, or oily cast iron – even under difficult conditions.
Excellent machinability: The weld seam is easy to drill, mill, or tap – ideal for applications where precision is required.
Time and cost-saving: Less post-processing, no expensive preheating procedures, and a lower risk of repair failure.
Universally applicable: Suitable for grey cast iron, nodular cast iron (GGG), malleable cast iron, and combinations of cast iron with steel.
Cold welding without cracks: Magna 777 makes it possible to weld without preheating – ideal for sensitive repairs or situations where thermal distortion is unacceptable.
