By means of swaging it is possible to produce composites of steel (as coats) and heavy-metal alloys (as rods). In case of cold forming processes, there are strain hardening effects within both materials. In opposite to the steel the heavy-metal alloy may be characterized by a dramatic loss in ductility. Heat treatment processes lead to revocery and recrystallisation of the heavy-metal alloy which concerns the tungsten particles as well as the matrix material, but there is no chance to create a material similar to the delivery condition.
