Magna 720
Magna 720 Superior Electrode for Dirty or Burnt Cast Iron
- Welds cast iron that is so greasy, rusty, and burnt that standard electrodes cannot even join.
- Has a unique “Quick Freeze Action,” meaning slag solidifies before damage or porosity occurs.
- The colour and coefficient of expansion and elongation closely match cast iron to ensure a professional finish.
- Makes vertical and overhead welding easy because no drips form.
- Seals the contamination so that welding can continue.
Welds cast iron without preheating
Tensile strength weld 49,781.55 psi (343.23 MPa)
Demonstrates remarkably high crack resistance
Elongation/Extension : equal to cast iron
