The mechanical alloying process has been used to prepare nanocrystalline Cu_{70}Fe_{18}Co_{12} alloy from elemental Cu, Fe and Co powders in a planetary ball mill under argon atmosphere. The interdiffusion of Cu, Fe and Co leads to a heterogeneous solid solution with Cu-Fe-Co rich environments after 12 h of milling. The end product is a mixture of a highly disordered structure, fcc-Cu (Fe-Co), phase having different microstructural and structural parameters. For all the elaborate series, the evolution of coercive field and the remanence according to the time of milling is analyzed. The coercivity, H_{c}, decreases rapidly up to 8 h of milling to about 0.3 A/m and then the coercivity, increases to a maximum at 54 h. The influence of the time of milling at the resistivity of these alloys is shown.
