Ti-6Al-4V (Grade 5) is the most-used titanium alloy in aerospace and medical applications. It combines exceptional strength-to-weight, biocompatibility, and corrosion resistance with the well-known cost and machinability premiums.
Mechanical and physical properties
| Property | Value |
|---|---|
| Tensile strength | 950 MPa |
| Yield strength | 880 MPa |
| Elongation at break | 14% |
| Density | 4.43 g/cm³ |
| Modulus | 113.8 GPa |
| Hardness | 36 HRC |
| Max service temperature | 400 °C |
| Machinability rating | Difficult |
Typical applications
- Aerospace structural fittings.
- Medical implants and instruments.
- High-performance fasteners.
- Marine drive shafts and propellers.
Cost reality
Stock cost is roughly 5-10x aluminum and machining is 2-3x slower. Use titanium when strength-to-weight or biocompatibility is essential — not as a 'premium' choice.
