Where does the US get most of its titanium?

Could you please clarify for me where the United States primarily sources its titanium from? I'm curious about the geography and potentially the mining processes involved in this vital resource for industries like aerospace and construction. It would be interesting to learn if the country relies heavily on domestic production or if it imports a significant portion of its titanium needs from abroad. Additionally, I'm wondering if there are any geopolitical or economic factors that influence these sourcing decisions.
