Magna 770
Magna 770 Ultra Strong Electrode for Cast Iron
- Perfectly welds all types of cast iron, as well as wrought iron, grey cast iron, nodular cast iron, Meehanite cast iron, and also welds steel to cast iron.
- 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.
- Has the highest elongation ever incorporated into a cast iron electrode, thereby preventing cracking and tearing.
160 Brinell hardness
Tensile strength weld 58,500 psi (403.31 MPa)
Demonstrates remarkably high crack resistance
Elongation/Extension : equal to cast iron
Properties Magna 770 Ultra Strong Electrode for Cast Iron
Magna 770 Ultra Strong Electrode for Cast Iron welds virtually all types of cast iron.
- Magna 770 can be welded with both AC and DC.
- Magna 770 easily welds oil-soaked cast iron, chemically soaked cast iron, and other contaminated cast iron.
- Magna 770 is machinable without problem.
- Magna 770 welds in all positions.
- Magna 770 gives extreme tensile strength, making the weld ductile and non-cracking.
Application Magna 770 Ultra Strong Electrode for Cast Iron
Magna 770 Ultra Strong Electrode for Cast Iron
Magna 770 welds successfully without preheating. However, preheating is desirable on large components.
Magna 770 AC – DC is the only electrode specially designed for welding all types of cast iron in maintenance applications.
