| Silicon (Si) | 12.0–13.0% | Low thermal expansion, wear resistance |
| Copper (Cu) | 2.5–3.5% | Strength and high-temperature stability |
| Magnesium (Mg) | 0.6–0.9% | Precipitation hardening |
| Nickel (Ni) | 1.5–2.5% | Elevated-temperature strength |
| Manganese (Mn) | 0.15–0.35% | Inter metallic/impurity control |
| Titanium (Ti) | 0.05–0.15% | Grain refinement |
| Zirconium (Zr) | 0.05–0.15% | Micro structural stability |
| Iron (Fe) | ≤0.35% preferred | Minimize detrimental Fe phases |
| Zinc (Zn) | ≤0.20% | Keep controlled |
| Other impurities | As low as practicable | Fatigue/reliability |
