Isotopes of titanium
The five stable Titanium isotopes are used for a wide range of studies and applications. Ti-48 is used for the production of the radioisotope V-48 which is used in nutritional studies and for calibrating PET instrumentation. Ti-47 is occasionally used as an alternative precursor for the production of V-48. Ti-50 is used in the production of super heavy elements whereby Lead or Bismuth targets are bombarded with Ti-50. Finally, Ti-49 is used in the production of the radioisotope V-49. Titanium isotopes can be obtained from Trace Sciences International.
Naturally occurring isotopes
This table shows information about naturally occuring isotopes, their atomic masses, their natural abundances, their nuclear spins, and their magnetic moments. Further data for radioisotopes (radioactive isotopes) of titanium are listed (including any which occur naturally) below.

In the above picture, the most intense ion is set to 100% since this corresponds best to the output from a mass spectrometer. This is not to be confused with the relative percentage isotope abundances which total 100% for all the naturally occurring isotopes.
