>A process has been developed for extruding the aluminum sheath directly on the core material. The process is accomplished by a vertical hydraulic press forcing prehented aluminum billets into a converging chamber of a die-block arrangment. Metal flows around the core material and welds into a continuous sheath over the core as the core is guided horizontally through the die. The size of the die aperture determines the thickness of the cladding. A solid aluminum plug is extruded prior to the core entering the die and again after the core has passed through the die. These plugs act as end seals, eliminating the need for welded end-closures. (A.C.)
