A cost effective and convenient method for preparing nanopowders of Fe-Co alloy has been developed. The finely divided powders of Fe-Co alloy in the form of solid-solution were obtained in the FeSO4•(NH4)2SO4 and CoSO4•(NH4)2SO4 mixed solution by the reduction of aluminum powders at 40 ℃ and pH～3.The product of Fe-Co alloy was identified by XRD method and the calculated size of these nanoparticles was about 15 nm. Meanwhile, the compositions of obtained samples were analyzed by ICP-AES method. Experiment indicated that the composition of the alloy could be easily controlled by changing the mass ratio of Fe2＋:Co2＋ in the solution.
