- Ideal for automotive, marine, and general fabrication applications
- Suitable for AC or DC welding with argon shielding gas
Chemical Composition (Typical)
- Silicon (Si): 4.5–6.0% – enhances fluidity and reduces cracking
- Iron (Fe): ≤ 0.8% – maintains weld integrity
- Copper (Cu): ≤ 0.3% – improves strength without compromising ductility
- Manganese (Mn): ≤ 0.05% – supports grain structure
- Magnesium (Mg): ≤ 0.05% – balances strength and corrosion resistance
- Zinc (Zn): ≤ 0.10% – minimizes porosity
- Titanium (Ti): ≤ 0.20% – refines grain and improves weld quality
- Aluminium (Al): Balance – base metal for optimal compatibility
