uber-bling. Should be ok I think. I'd use some copper grease anyhow, but as above, the two metals are similar (may not be the exact same Ti-alloy however).
With every titanium part, it’s really important to use plenty of anti-seize compound at every point and in all places where titanium comes into contact with any
other metal surface, including other titanium.
Ally suffers from galling more.
Ti is prone to a chemical reaction with dissimilar metals which can result in the two parts literally "weld" themselves together, not good when you're talking about an expensive Ti frame & components.
Plenty of suitable lube/anti-seize and perhaps more regular maintainance and all should be well.
I've not had a Ti frame before, but have had Ti components/bolts etc and after using "Ti-Prep" or Copper grease have never had any issues.
My Ibis ti quill stem was supplied with a steel bolt and the blurb in the packet said to not switch to a ti bolt due to it galling. Oh, and I'd use Chemodex Nickel 'Never Sieze' over copper grease. It has better properties and is the same dull metallic colour as ti too...winner
