What's up with that? Surely there are those who would pay premium
dollar for a lightweight but extremely strong chain lock made of
titanium. If I understand things correctly, titanium should be
unbreakable, right? I mean, it's the stuff tank armor is made of! But
I read instead that ti locks aren't as strong as steel, actually!

WTF?!

Pure titanium is not all that strong. Used in an alloy, it can make a
stronger, lighter product than steel...but the expense of making the
material and working it can be amazingly high.

Do you want to pay DoD prices for your chain? If so, then I suspect
that you can get a near-bombproof Ti-alloy chain somewhere. But I
suspect that a spare bike might be cheaper, and a good conventional
hardened chain would be a lot more cost-effective.
