Grade 9 titanium alloys Seamless Heat Exchanger Tube

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
