    Abstract: An inexpensive transitional connector, suitable for use in joining aluminum tubes to tubes formed of a variety of other materials which cannot be readily soldered, brazed or welded to aluminum, is shown to comprise steel and aluminum tubular elements disposed in coaxial relation to each other, the tubular elements being metallurgically bonded together. Preferably, the transitional connector incorporates a silicon-aluminum layer between the aluminum and steel elements thereof to retard formation of aluminum-iron intermetallic compounds at the interface between the aluminum and steel elements during soldering, brazing or welding of the transitional connector. If desired, the steel element of the connector is clad with a layer of copper.
