| Property | Value |
|---|---|
| Ultimate Tensile Strength (min) | 895 MPa (130 ksi) |
| Yield Strength (0.2%, min) | 828 MPa (120 ksi) |
| Elongation (min) | 10 % |
- Minimum properties per ASTM B348 apply to bar up to 3 in (76 mm); larger sections are by agreement.
- Minimum properties per ASTM B265 apply to plate up to 1 in (25 mm) thick; thicker plate is by agreement.
- Density is a typical value, not a specification requirement.

Frequently Asked Questions
What is Grade 5 titanium (Ti-6Al-4V) used for?
Aerospace structures and fasteners, bicycle frames, marine and motorsport hardware, where high strength for its weight matters.
What is the difference between Grade 5 and Grade 23 titanium?
Grade 23 (Ti-6Al-4V ELI) has lower oxygen, nitrogen, carbon and iron limits than Grade 5, which improves ductility and fracture toughness. Its ASTM B348 minimums are slightly lower: 828 MPa (120 ksi) tensile against 895 MPa (130 ksi).
