Titanium Grade 5 is an alpha-beta titanium alloy containing about 6% aluminium and 4% vanadium (Ti-6Al-4V). This datasheet presents the material within the American (ASTM / ASME / UNS) standard system.
The most widely used titanium alloy in the world — accounting for roughly half of all titanium consumed — Titanium Grade 5 combines high specific strength, excellent corrosion resistance, good weldability and excellent biocompatibility. The aluminium stabilises and strengthens the alpha phase while the vanadium stabilises the beta phase, giving a two-phase alpha-beta microstructure that, unlike the commercially pure and near-alpha grades, can be strengthened by heat treatment (solution treatment and ageing) as well as used in the annealed condition. It offers high strength at low-to-moderate temperatures (usable to about 400 °C), good fatigue and creep resistance, and a low elastic modulus. It is normally supplied mill-annealed for the best combination of strength, toughness and ductility.
Typical applications include aircraft turbine-engine components, airframe and spacecraft structures, aerospace fasteners, pressure vessels and rocket cases, medical implants and prostheses, and high-performance marine and automotive parts.

Confirm against the mill test report. Strength can be raised by solution treatment and ageing (STA), generally in sections up to about 25 mm.

Corrosion resistance is characteristic of titanium — excellent in seawater, marine atmospheres and oxidizing media — combined with high strength and excellent biocompatibility for implants.
An alpha-beta titanium alloy; can be used annealed or strengthened by solution treatment and ageing.
Solution Treatment Solution treat at approximately 900–955 °C (below the beta transus) and quench. Mill annealing (~700–785 °C, air cool) is used for the standard annealed condition.
Ageing Age at approximately 480–595 °C to precipitate fine alpha and develop higher strength (STA condition). The response to ageing is effective in sections up to about 25 mm. Protect from oxygen, nitrogen and hydrogen pickup at temperature.
Weldable by inert-gas processes; the weld pool and cooling weld must be fully shielded from atmospheric contamination, which causes embrittlement. Post-weld stress relief or annealing is commonly applied.

|---|---|---|
| GTAW / TIG | Good | AWS A5.16 ERTi-5 (matching) |

Use full inert-gas shielding and clean, contamination-free surfaces; avoid hydrogen, oxygen and nitrogen pickup. Post-weld heat treatment is common.
