Grade 9 titanium alloys (3-2.5) are typically the preferred choice for numerous applications across various industries, particularly suitable for manufacturing high-tech products ranging from medical pacemakers to aerospace cellular devices.
The mechanical properties of Grade 9 titanium alloys far surpass those of pure titanium. One of the main advantages of this titanium alloy, containing 3% aluminum and 2.5% vanadium, is its cold-working capability, unlike Ti-6-4.

The Ti-3-2.5 alloy is characterized by
Excellent resistance to general corrosion in seawater applications
High mechanical strength, superior strength to weight ratio
Resistant 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 from Alleima's proprietary processing that controls crystal texture
