Actually I suspect the largest amount of Titanium was probably used on
the SR-71. It is a Titanium Aircraft.
Titanium is a very difficult metal to machine, hence it tends to be
utilized in places where extreme performance is required, and justifies
the very high fabrication costs.
I believe the fan disks in most large tubo fan engines are titanium (at
least the one that flew out of a CF6 that caused the Sioux City crash
landing was)..I doubt there is a lot of titanium in most civilian
aircraft outside the engines.
