Grade 5 Titanium (Ti 6Al 4V)
Jan 15, 2026
What is GR5 titanium?
Ti-6Al-4V (Grade 5), classed as an alpha-beta alloy, is the most widely used of the high strength titanium alloys. The alloy combines its good mechanical strength and low density (4.42 kg/dm³) with excellent corrosion resistance in many media.
Grade 5 titanium is fully heat treatable (solution heat treatment plus aging) in sections up to 25mm and can be employed up to around 400°C. Ti-6Al-4V ELI (Grade 23) has a reduced oxygen content (0.13% max.) compared with Grade 5. This confers improved ductility and fracture toughness with some reduction in mechanical strength. Uses include fracture critical airframe structures and for offshore tubulars.

Corrosion Resistance
Grade 5 titanium offers excellent resistance to many marine and offshore oil & gas environments. Titanium and its alloys resist a wide range of acid conditions being highly resistant to oxidising acids, possessing useful resistance to reducing acids and offering good resistance to most organic acids at lower concentrations and temperatures. Titanium should not be used with red fuming nitric acid and is rapidly attacked by hydrofluoric acid.
The addition of 0.05% palladium (grade 24), 0.1% ruthenium (grade 29) or 0.05% palladium and 0.5% nickel (grade 25) significantly increases corrosion resistance in reducing acid chloride and sour environments, raising the threshold temperature to well over 200°C.

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)
