Machining Ti is a bear, but any decent machinist should be able to do it.
You may pay a little more of course and I donít believe work
hardening etc is an issue.
Ti seems to have this magic aura around it, but to a machinist itís just another metal, just requires slower speeds and feeds Iíve been told.
Titanium made my chainplates, but that was mostly bending and welding, as you already have the metal I donít think they would be a source. They were a lot less expensive than I was prepared for.
Most often Ti is available in grade 2 or grade 5, either is acceptable of course with 2 being a little weaker but more corrosion
resistant, 5 being stronger but more susceptible.
99% of Ti used in Aerospace ps grade 5. Grade 2 is stronger than the stainless it replaces so if itís the same size strength isnít an issue.
