Titanium

[edKENdance]

I remember having some good information a few years back from Rodenstock on the different types of titanium(s) used in the manufacture of frames. It's long gone. We sell higher end titanium frames but I am lacking the proper information that would really help to distinguish the reason that a titanium frame we sell for XXX is different than a titanium frame from a big box store for X. Other than the fact that you can feel the difference. Does anyone have a link or some essential info about purity, composition, etc...? Appreciated.

I know beta titanium is the purest stable composition of titanium in frames. Or at least thats what Charmant tells me.

EDIT: I mean they say their Beta titanium is the purest of the ones used in frames.

I can kind of understand the appeal of beta ti. It's always manufactured so thin though. A lot of our selection has frame fronts that range from 2-4mm in thickness. The temples are a lot thinner though and more flexible. I know Blackfin pairs solid titanium fronts with beta Ti temples that are ridiculously cool.

Just about everything that you could ask about titanium alloys will be found here:

If you want to know which alloy is used in a specific frame just ask the manufacturer. Lots of luck with that one.

The rep knows less than you do however he is probably very well versed in the fine art of BS.

Thanks for the link Dick.

Does anyone know if the bridge on say a Flexon frame is welded or glued to the non titanium eyewire?

(Sorry for the tangent eDKEN)

The tangent is relevant since memory metal is a titanium/nickel mix. If my memory serves me correct I believe Jerry Huang posted about the bridge piece on a memory metal frame like a Flexon is actually held in by kinks or crimps on that part of the nasal that holds the bridge. Please correct me if I'm wrong.
