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. |
