I saw this discussion with a guy from the titanium industry because
of the case for the new Mac Powerbook. It raised some OM issues for
me.
The type of titanium used for the PB G4 has been described as
'CP-1", or commercially pure, grade 1 titanium. This is most
commonly used in the aerospace industry, and this grade does not
contain other metal alloys. The color can best be described as "gun
metal gray". Is this the color of the PB G4? - it appears lighter to
me. That could imply that the metal has been anodized - titanium can
be anodized very easily and the result is any color under the
rainbow that one wishes. The Wintel demos that I mentioned earlier
have been prepared in many different colors. Titanium will scratch
easily - yes, it will scratch easily, and then it will look like
crap. I assume that Apple has placed some form of protective coating
over the metal to ensure it does not. The existence of a coating
would also help in regard to fingerprints and other dirt - CP-1
titanium has a very flat looking gun metal gray color that collects
fingerprints, but cleans up well.
Since I have one of the notoriously flaky black painted OM4Ts I do
not have any experience with the so called champagne models. Do they
have a coating or anodizing to protect it from scratches and
fingerprints? The ones I have seen have an odd texture and have a
warmer color of gray than what I think of with gun metal gray.
