Abstract

The invention relates to an amorphous metal alloy which may be used in the field of mechanical applications, in particular as a spring. This amorphous metal alloy corresponds to the formula FeaCObNicNbdVeBfTag in which: 0≦a≦70; 0≦b≦70; 8<c≦60; 1≦d≦19; 1≦e<≦10; 12≦f≦25; 0≦g≦5; with 20≦a+b≦70; 50≦a+b+c≦90; 5≦d+e≦20; and a+b+c+d+e+f+g=100.
