Products Description
Excellent cold formability, 20-50% higher tensile properties than CP titanium grades. Primarily used in aircraft hydraulic systems. Titanium Ti3Al2.5V (grade 9) or more simply known as Ti-3-2.5 is commonly grouped with the commercially pure grades due to it's ability to be cold rolled. The strength of Ti3al2.5V (Ti-3-2.5) falls between Grade 4 and Grade 5. However, Ti3Al2.5V (grade 9) can be used at higher temperatures than Grade 1, Grade 2, Grade 3 and Grade 4. Applications for Ti3Al2.5V are Aerospace, Chemical Processing, Medical, Marine, Automotive industries, etc.
