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)

Technological properties

Property
Application areas

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.

Corrosion properties

Excellent Resistance to pitting and crevice / erosion corrosion
