Zusammenfassung:	The method of this disclosure comprises the production of solid complex shapes of substantially uniform cross-sectional shape throughout their length from filled billets by extrusion of the latter with either the replica or filler, which together comprise the billets, being formed from a plurality of stacked, thin plates. The plates are preferably indexed and keyed together to maintain the desired complex shape throughout the extrusion step.
