Abstract (en)

[origin: EP1154026A1] A method for the fabrication of composite tin-tungsten elements having a thickness between 1 and 6 mm from a mixture of tin and tungsten powders consists of directly extruding the mixture of powders in the solid state to form a wire with a thickness of 1 to 6 mm, with a drawing speed of less than or equal to 80 mm/s. The wire produced is then cut into sections that are then stamped to obtain the desired shape. An Independent claim is included for the production of a composite tin-tungsten wire from a mixture of tin and tungsten powders.
