Hi all,
I have worked with titanium a bit. It is very gummy to machine, but the
surface finish can be a variety of textures, depending on how it is worked.
It can be buffed to a very high luster. As a comparison to the plating on
musical instruments, silver tends to be "white", chrome is "blue" and nickel
is "black". I would characterize polished Ti to be a dark gray/brown.
The old Teledyne Titan Titanium bike frames were raw Ti as I remember, and
were a real headache to keep looking nice. Every fingerprint and smudge
would show up on them. They seemed to be a dull, but not bead-blasted
finish. The frame was very whippy, great for light riders doing steady time
trial speeds but not good for gorillas doing sprints.
