The subject of the invention is a particularly simple and inexpensive process for manufacturing tin/tungsten composite elements having a thickness of between 1 mm and 6 mm, such as spherical shot for hunting cartridges or fishing sinkers, from a tin/tungsten powder blend. The powder blend is extruded, in the solid state, directly into a wire whose thickness is between 1 mm and 6 mm with an extrusion rate<=80 mm/s. Next, the wire is cut into pieces which are then forged to the desired shape, especially into spheres. The subject of the invention is also the aforementioned process for obtaining the wire.
