Titanium Grade 9

Share

Ti Grade 9, is sometimes referred to as "half 6-4". It offers 20-50% higher strength than C.P. grades, but is more formable and weldable than Ti-6AI-4V. Grade 9 combines strength, weldability and formability. The alloy has excellent formability plus higher tensile strength than the strongest unalloyed grade.
