Ti Gr5 (Grade 5)
Jan 15, 2026
The chemical composition of Ti Gr5 alloy includes 90% titanium, 6% aluminum, and 4% vanadium. Ti Gr5 titanium is often preferred in various applications due to its high strength, low density, and corrosion resistance.
What is Ti Gr5 (Gr5, Titanium Grade 5, Ti-6Al-4V) Material?
Ti Gr5, commonly known as Grade 5 titanium or Ti-6Al-4V, is a titanium alloy produced in accordance with the ASTM B265 standard. The chemical composition of Ti Gr5 alloy includes 90% titanium, 6% aluminum, and 4% vanadium. This alloy is the most widely used type of titanium. Ti Gr5 titanium is often preferred in various applications due to its high strength, low density, and corrosion resistance. In addition to these properties, Ti Gr5 provides good wear resistance.
Thanks to its mechanical properties, Ti Gr5 titanium maintains the advantages of high strength and low density, while also offering better wear resistance. The alloy can be heat-treated to further enhance its strength.

GR5 Titanium vs. GR2 Titanium: Comparison and Selection Guide
| Feature / Property | GR2 Titanium (Commercially Pure) | GR5 Titanium (Ti-6Al-4V) |
|---|---|---|
| Main Composition | 99.2%+ Titanium (Pure) | Alloy: 90% Ti, 6% Al, 4% V |
| Key Characteristic | Excellent corrosion resistance, formability, weldability | High strength-to-weight ratio, heat resistance |
| Tensile Strength | ~345 MPa (~50 ksi) | ~895 MPa (~130 ksi) |
| Yield Strength | ~275 MPa (~40 ksi) | ~825 MPa (~120 ksi) |
| Density | ~4.51 g/cm³ | ~4.43 g/cm³ |
| Maximum Service Temp | ~300°C (~570°F) | ~400°C (~750°F) for long-term |
| Corrosion Resistance | Excellent, widely used in chemical/ marine | Very good, but slightly less than GR2 in some media |
| Fabrication (Machinability) | Good (easier to machine) | Fair (more challenging, requires proper technique) |
| Weldability | Excellent (common methods) | Good (requires proper shielding, post-weld heat treatment) |
| Relative Cost | Lower | Higher (due to alloying elements & processing) |
Choose GR2 Titanium When:
Primary need is corrosion resistance – for chemical processing, seawater, chloride environments, and marine applications.
Require excellent formability and weldability – for complex shapes, vessels, heat exchangers, and piping systems.
Working with moderate strength requirements – where high strength is not critical (e.g., architectural, consumer goods).
Budget is a constraint – GR2 is the most economical and widely available titanium grade.
Application involves:
Chemical processing equipment
Marine and offshore components
Heat exchangers and condenser tubes
Medical implants (non-load bearing)
Architectural cladding
Choose GR5 (Ti-6Al-4V) Titanium When:
High strength and low weight are critical – for aerospace frames, engine components, and structural parts.
Require good strength at elevated temperatures – up to about 400°C (750°F).
Application demands fatigue resistance – for rotating or cyclically loaded parts.
Medical implants requiring load-bearing capability – such as joint replacements, bone screws, and dental implants.
Application involves:
Aircraft and aerospace components
High-performance automotive parts
Critical medical implants
Military and defense equipment
Sports equipment (high-end bicycles, golf clubs)
