Titanium Alloy Grade 5 /Ti-6Al-4V
Jan 15, 2026
What is GR5 titanium?
Titanium Grade 5 (Ti6Al-4V) is the most commonly used alloy. Ti6Al4V is significantly stronger than other commercially pure titanium whilst still retaining the same stiffness and thermal properties (excluding thermal conductivity). Titanium Grade 5 extensively used in Aerospace, Medical, Marine and Chemical Processing.

FAQ
| What is the chemical composition of GR5 titanium? The nominal chemical composition of GR5 titanium is Titanium (Ti) balance, Aluminum (Al) 5.5-6.75%, Vanadium (V) 3.5-4.5%, with strict limits on impurities like Iron (Fe), Oxygen (O), Carbon (C), and Nitrogen (N). |
| What are the key mechanical properties of GR5 titanium? Typical minimum mechanical properties for annealed GR5 titanium are: Tensile Strength ≥ 895 MPa, Yield Strength ≥ 825 MPa, and Elongation ≥ 10%. Its strength can be increased through heat treatment. |
| What is the density of GR5 titanium? The density of GR5 titanium is approximately 4.43 g/cm³, which is about 60% of the density of steel, contributing to its high strength-to-weight ratio. |
| Can GR5 titanium be heat treated? Yes, GR5 titanium can be strengthened through solution treatment and aging (STA) processes, which enhance its mechanical properties compared to the annealed condition. |
| Is GR5 titanium corrosion resistant? Yes, GR5 titanium exhibits excellent corrosion resistance in many environments, including seawater, chloride solutions, and various chemical media, due to a stable, protective oxide film. |
| Can GR5 titanium be welded? Yes, GR5 titanium has good weldability using processes like Gas Tungsten Arc Welding (GTAW/TIG) and Electron Beam Welding (EBW), provided that strict shielding from atmospheric contamination is maintained. |
| 9. How does the strength of GR5 compare to commercially pure (CP) titanium grades? GR5 titanium has significantly higher strength than CP titanium grades (such as GR2 or GR4). GR5 is a medium-strength alloy, whereas CP grades are lower in strength but often more formable. |
| What are the main industries that use GR5 titanium? The primary industries using GR5 titanium are aerospace (for airframe and engine components), medical (for orthopedic and dental implants), marine, chemical processing, and high-performance automotive. |
| Is GR5 titanium biocompatible? Yes, GR5 titanium (Ti-6Al-4V) is considered biocompatible and is a standard material for permanent surgical implants like joint replacements and bone plates, though there is ongoing research into vanadium-free alloys for certain long-term implants. |
| 12. What are the machining considerations for GR5 titanium? Machining GR5 titanium requires sharp tools, lower cutting speeds, high feed rates, ample coolant, and a rigid setup to manage its low thermal conductivity and tendency to work-harden. |
