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
