Titanium Grade 9 is an alpha–beta titanium alloy with a lower alloy content than Grade 5, which provides low weight, good corrosion resistance and improved formability. Titanium alloy Gr9 can be used at higher temperatures than commercially pure titanium grades 1-4, as it can be cold rolled. Grade 9 is often used in the bicycle industry, heat exchangers, aerospace structures and marine applications – especially where formability, weldability and strength per weight are critical.
Recommended filler metal for welding: Ti-3Al-2.5V with inert gas shielding, e.g. argon.
General material description:
Type: α+β titanium alloy (~3% Al, ~2.5% V)
Structure: Mixed structure with more alpha than Ti-6Al-4V → better cold workability
Developed for: Applications where low weight, good strength and weldability are required, especially in tubular form
Alternative names: Titanium Grade 9, Ti-3Al-2.5V, UNS R56320, Werkstoffnr 3.7195, ASTM B338
Key advantages:
Low density + good strength (~600 MPa) → high strength/weight ratio
Excellent weldability – even in field applications without advanced equipment
Good formability – can be cold formed into complex shapes
Good corrosion resistance in seawater, chlorides and oxidizing environments
High fatigue strength – cyclically stable material
Disadvantages / Limitations:
Lower strength than Grade 5 – not suitable for extremely high-stress parts
Not optimal at high temperature (>350–400 °C)
Lower creep resistance compared to heavier hardenable alloys (Grade 5, 23)
Applications by industry and value:
Aviation industry: Pressure pipes, fuel systems – strength + weldability
Marine / Offshore: Pipe systems, couplings – seawater resistance
Bicycles / Sports equipment: Frame tubes, components – light weight + stiffness
Heat exchangers / Power industry: Pipes and plates – corrosion resistance + weldability
Medical technology: Non-structural parts – light weight, good biocompatibility
General corrosion description:
Passive oxide film provides good resistance to corrosion in seawater, chlorides and acids
Resistant to stress corrosion cracking in chlorides
Not susceptible to hydrogen-induced embrittlement in normal use
Corrosion environments where the material performs well:
Seawater and marine environments (incl. underwater use)
Mild to moderate acids (organic, oxidizing)
Chloride environments, salt spray and air with high humidity
Sterile environments / high purity
Corrosion environments where the material should be avoided:
Hydrofluoric acid (HF)
Strong reducing acids at high temperature (e.g. hot HCl)
Standing acids with low pH and low oxygen content
Technical material properties (annealed condition, ASTM B338):
Property (Typical value)
Yield strength (0.2%): ~450–550 MPa
Tensile strength: ~620–690 MPa
Elongation at break: ~18–25%
Density: ~4.48 g/cm³
Modulus of elasticity: ~105 GPa
Thermal conductivity: ~7–8 W/m·K
Usage temperature: Rec. ≤ 350°C in long-term application
Weldability: Very good – requires simple inert gas environment
Machinability: Good – especially cold working, bending, rolling
