<p>Disclosed are amorphous, ductile brazing foils with a composition consisting essentially of FeRestNiaCrbSicBdPe, wherein 0 atomic %≰a<25 atomic %; 0 atomic %≰b≰15 atomic %; 1 atomic %≰c≰10 atomic %; 4 atomic %≰d≰15 atomic %; 1 atomic %≰e≰9 atomic %; any impurities≰0.5 atomic %; rest Fe, wherein 2 atomic %≰c+e≰10 atomic % and 15 atomic %≰c+d+e≰22 atomic %, or consisting essentially of FeRestNiaCrbMofCugSicBdPe, wherein 0 atomic %≰a<25 atomic %; 0 atomic %≰b≰15 atomic %; 1 atomic %<c≰10 atomic %; 4 atomic %≰d≰15 atomic %; 1 atomic %≰e≰9 atomic %; 0 atomic %<f≰3 atomic %; 0 atomic %≰g≰3 atomic %; any impurities≰0.5 atomic %; rest Fe, wherein 2 atomic %≰c+e≰10 atomic % and 15 atomic %≰c+d+e≰22 atomic %. Also disclosed are brazed objects formed using these foils, particularly exhaust gas recirculation coolers and oil coolers, and methods for making the brazing foils and for making the brazed parts.</p> |
