Pure elemental titanium has much less desirable material properties than various titanium alloys which are what you encounter most commonly. It is very uncommon to encounter elemental titanium outside of a chemistry lab.
I have some titanium crafting wire. Should be easy to find on Amazon or similar. It's a little surreal - looks similar to a roll of steel wire, but feels as lightweight as PLA. Basically the real-world version of mithril.
