Cheap titanium bikes are high on my list but I think the killer application is titanium hinges. Springs will last a lifetime.

Looks like this is starting to happen alreadt: https://www.alibaba.com/showroom/titanium-hinges.html

$0.25 for a hinge

Titanium is light, but my favorite thing is it is next to impossible to bend. So anything that shouldn't bend will be better with titanium.
