Ti3Al2.5V (Grade 9)
This alloy is sometimes referred to as ‘half 6-4’. It offers 20 to 50% higher strength than commercially pure grades, but is more formable and weldable than Ti6Al4V. It is principally used as tubing in aircraft engine hydraulic systems, for high strength corrosion resisting applications such as golf club shafts, tennis rackets, bicycle frames etc.
