I just got some bottle cages that came with Ti screws for my aluminum frame. Can I use my regular Phil Wood grease (http://www.philwood.com/webcatolog/page18.htm) on the Ti screws, or do I need special grease for this (copper-based?)?

I would use anti-seize compound, which is the copper-based grease you refer to. Anytime ti is involved, anti-seize is best-

Yup, anti-sieze is the stuff. You should use it any time different metals thread together. bk

^^ i think usually you don't need it between aluminum and steel - grease is enough to prevent binding. It's titanium that seems to really like to bind, so you need the anti-seize for that.

For titanium, nickel anti-seize compound is preferred.

Yep, ti is bad about not playing well with other metals. On a bicycle, grease will do except when ti is involved-
