A method for producing a metal film from an alloy consisting of (in % by mass) W 5 to 30 %, wherein W can be completely or partly replaced by Mo, Mg 0.0001 to 0.050 %, wherein Mg can be completely or partly replaced by Ca, Ti max. 0.10 % Al max. 0.10 % B max. 0.020 % Fe max. 1,0 % Co max. 1,0 % Mn max. 0.20 % Si max. 0.20 % Cr, Cu, Nb respectively max. 0.20 % P max. 0.020 % C max. 0.050 % N max. 0.020 % S max. 0.020 % Ni rest (> 50 %) as well as the usual impurities resulting from the smelting process comprising the following process steps: (a) an amount of more than one ton of the alloy will be smelted in a vacuum induction furnace or openly in an induction or electric arc furnace, followed by a treatment in a VOD or VLF installation, (b) afterwards, the alloy will be cast into ingots, electrodes or as continuous casting for forming a primary product, optionally followed by a one-time or repeated remelting by means of VAR and/or ESU, (c) afterwards, the primary product will be optionally annealed at temperatures comprised between 800 and 1350°C during a period of 1 h through 300 h in air or protective gas, (d) then, the primary product will be hot-formed, especially hot-rolled, at temperatures comprised between 1300°C and 600°C, wherein the thickness of the original material will be reduced by the factor 1.5 - 200, such that the primary product will have a thickness comprised between 1 and 100 mm after the forming and is not recrystallized and/or recovered and/or is (dynamically) recrystallized with a grain size of less than 300 μm, in particular less than 150 μm, (e) the primary product will afterwards be stained and/or grinded, (f) then, for producing a film, the primary product will be cold-formed to a final thickness comprised between 10 and 300 μm, in particular between 40 and 150 μm, with a degree of deformation of more than 90 %, wherein the cold-forming is carried out with rolls having a defined surface for setting roughnesses of less than 2 μm, (g) after the cold-forming the film will be cut into strips of 5 to 300 mm, (h) afterwards, the film strips will be annealed in protective gas at temperatures comprised between 600 and 1200°C during 1 sec to 5 h in a continuous furnace, (i) wherein the annealed film-like material will be recrystallized and comprise a high proportion of cubic texture after this annealing.
