Easilyled,
Almost no one other than a machinist factors tooling wear & cost into a titanium light ... sounds to me like you have some machine experience. Tool wear on Grade 2 (commercially pure) titanium is far less than Grade 5 (Ti-6Al-4V) but Grade 2 has far less strength - aluminum alloy 6061 is 90% as strong in ultimate tensile strength as Grade 2. Grade 5 is 276% stronger than Grade 2 (source data from ASM Material Data Sheets).
I wish I had some machine experience precisionworks, but alas I don't. I based my answer on what I've gleaned from the great machinists on CPF, people whose skills I admire immensely.
