Titanium Grade 5
Jan 15, 2026
What is GR5 titanium?
This alpha-beta alloy is the workhorse alloy of the titanium industry. Titanium grade 5 has good tensile properties at ambient temperature and a useful creep resistance up to 300°C. Resistance to fatigue and crack propagation is excellent. Like most titanium alloys, Grade 5 has outstanding resistance to corrosion in most natural and many industrial process environments.
The ability to age harden this alloy makes it a good choice for such applications as springs and fasteners.

Applications
Titanium Grade 5 is a pure alpha-beta titanium with aluminum as the alpha stabilizer and vanadium as the beta stabilizer. This alloy is primarily use for corrosion resistance and is the most widely used specification in all product forms. The alloy features very high strength, good corrosion resistance, excellent strength to weight ratio and high strength at cryogenic temperatures.

Weldability
Grade 5 alloy is easily welded in the annealed condition, or in the solution and partially aged condition, with aging being completed during the post weld heat treatment. Precautions must be taken to prevent oxygen, nitrogen, and hydrogen contamination. Fusion welding can be done in inert gas filled chambers, or using inert gas welding of the molten metal and the adjacent heated zones using a trailing shield.
Spot, seam, and flash welding can be performed without resorting to protective atmospheres.

FAQ
| Why is GR5 titanium alloy so widely used? GR5 titanium alloy is widely used because it offers an optimal balance of high strength, good ductility, excellent corrosion resistance, and favorable weldability, making it versatile for demanding applications. |
| 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. |
