GNEE can provide the form
Products Description
Titanium Alloy ( 3AL/2.5V) Grade 9 is sometimes referred to as half Ti 6/4. It offers higher strengths than the commercially pure alloys , and is easier to form than the Ti 6AL/4V "work horse alloy". Its main available form is seamless tubing used in the aircraft and leisure industries such as bicycle frames and golf clubs etc . Typically this alloy is supplied in two Conditions Annealed and CWSR ( Cold Worked & Stress Relieved)
Applications
Used in aircraft applications where strength is required but weight is a critical factor. Ti-3Al-2.5V is used in tubular form since it has proven to be much more malleable than Ti-6-4 and has useful properties for applications in hydraulic systems. Ti-3Al-2.5V titanium tubing can be cold worked by standard tube manufacturing processes or supplied in the annealed condition. Other applications include, bicycle and wheel chairs frames.
