Titanium 3-2.5
Ti 3Al-2.5V (Grade 9)
Data Sheet
Titanium 3-2.5, Grade 9 is a near alpha, alpha-beta alloy. It offers much more strength than CP titanium, and unlike Ti 6-4 can be cold worked resulting in moderately high strength and good ductility. It is as weldable as the CP grades and has excellent resistance to corrosion.
