From page 205...
... Only steel, aluminum, or titanium are candidates for such transition structures. Titanium is the preferred choice because of its higher strength to weight ratio, its corrosion resistance, and its compatible expansion coefficient and electromotive force potential with graphite.

From page 206...
... The resulting thermal stresses with aluminum require that titanium be used. As a result, the 4 to 7 percent titanium use in today's predominantly aluminum commercial airframe (operating weight, empty, without engines)
