Titanium is a raw material, it can be collected somewhere, except North island, South island, Oslya. It could be Taiwan. The formula the titanium is steel + grey rock, according to the data base.

The one you manufacture is Titanium ALLOY, which does not require titanium, strangely. The gold ores needed can be found in Taiwan, and the white silvery needed can be found in Mayan cave, so titanium ALLOY is quite hard to get.
