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.
