2. Ti-6Al-4V Composition Explained
The strength and reliability of this alloy come from its precise chemical makeup.
Ti-6Al-4V Composition (%)
| Element | Percentage |
| Titanium (Ti) | Balance |
| Aluminum (Al) | 5.5 – 6.75% |
| Vanadium (V) | 3.5 – 4.5% |
| Iron (Fe) | ≤ 0.30% |
| Oxygen (O) | ≤ 0.20% |
| Carbon (C) | ≤ 0.08% |
| Nitrogen (N) | ≤ 0.05% |
Why This Composition Matters
