1. Material Profile
Grade 9 titanium alloy (Ti-3Al-2.5V, "3-2.5") is typically the preferred choice for numerous applications across various industries, particularly for high-tech products ranging from medical pacemakers to aerospace honeycomb devices. Its mechanical properties far surpass those of pure titanium. One of the main advantages of this alloy - containing 3% aluminum and 2.5% vanadium - is its cold-working capability, unlike Ti-6Al-4V.
2. Key Characteristics
Excellent resistance to general corrosion in seawater applications
High mechanical strength and superior strength-to-weight ratio
Resistance to stress corrosion cracking in chloride and sour-gas environments
Excellent resistance to pitting, crevice and erosion corrosion
Good formability and weldability
Very low thermal expansion
Excellent fatigue properties when crystal-texture-controlled processing is applied
3. Typical Composition
| Al | V | Fe (max) | C (max) | N (max) | H (max) | O (max) | Ti |
|---|---|---|---|---|---|---|---|
| 2.5-3.5 | 2.0-3.0 | 0.25 | 0.05 | 0.03 | 0.015 | 0.15 | Balance |
4. Supply Forms
Seamless pipe and seamless heat exchanger tube in standard sizes, per ASTM B338 / ASME SB338 (heat exchanger tube) and ASTM B861 (seamless pipe). Confirmed dimensions and wall thicknesses per project specification.
5. Applications
Heat exchangers and condensers (seawater-cooled)
Medical pacemaker components
Aerospace honeycomb and hydraulic systems
Chemical processing and marine engineering
