Ti-3Al-2.5V occupies the performance space between CP Grade 4 and Ti-6Al-4V — with approximately 50% higher strength than Grade 4 but better cold formability than Ti-6Al-4V. It is the standard material for aircraft hydraulic tubing (replacing...
Ti-3Al-2.5V occupies the performance space between CP Grade 4 and Ti-6Al-4V — with approximately 50% higher strength than Grade 4 but better cold formability than Ti-6Al-4V. It is the standard material for aircraft hydraulic tubing (replacing stainless steel for weight savings of ~40%) and high-end bicycle frames, golf club heads, and wheelchair frames.

Frequently Asked Questions
Can Ti-3Al-2.5V be cold-worked?
Yes — this is its primary advantage over Ti-6Al-4V. Ti-3Al-2.5V can be cold-drawn into seamless tubing, cold-rolled, and cold-formed to complex shapes. The lower aluminum and vanadium content (~50% of Ti-6Al-4V levels) provides a more ductile crystal structure amenable to cold working.
