     CP Titanium Grade 1
  Ti Grade 1 is the softest titanium with the highest ductility, good cold formability which gives Ti Grade 1 an excellent resistance from mild to high
oxidization.

  Titanium Alloy Grade 9
  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.
