This alloy is sometimes referred to as "half 6-4". It offers 20-50% higher strength tha C.P.grades, but is more
formable and weldable then Ti-6Al-4V. Grade9 combines strength,weldability and formability.
The alloy has excellent formability plus higher tensile strength than the strongest unalloyed grade.
