(FeCo)78Nb6B15Cu1 amorphous ribbons were prepared by a melt-quenching method; crystallization characteristics of the ribbons were tested by DSC, and accordingly annealing at 400, 500, 700 and 750 oC for 1 h were carried out. Crystallization behavior of the ribbons at different annealing temperatures was analyzed by XRD and SEM and the static magnetic parameters of the ribbon and the powder were measured by VSM. The results show that for the Hitperm alloy with a fixed composition, a suitable annealing temperature can control the grain size and phase ratio and adjust disorder magnetic moment of the grain surface, thereby improving the specific saturation magnetization of material. Moreover, the small nano-grain is favorable for depressing the coercivity. Due to the introduction of ultracrystallite when quenching, there is crystallization on the surface of the ribbon, which will worsen the static magnetic properties of materials to a certain extent
