Current distribution become nonuniform as the shape becomes more complicated, following the edge effect. In creating complex shapes with near net shapes by an electrodeposition, it is required to obtain the same characteristics from a wide current density range. In this study, we prepared bulk samples of Ni–Fe alloys by an electrodeposition with different current densities of 10–150 mA/cm2, and their microstructure, mechanical properties, and magnetic properties were examined. In the current density range of 25–150 mA/cm2, a relatively constant Fe content of 17–20 at% was observed. X-ray diffraction analysis showed that these alloys had a similar microstructure, which was a strong (200) texture and an average grain size of 17 nm. Tensile tests of these alloys also showed a constant tensile strength of 1.8–1.9 GPa and elongation of 10%. Furthermore, the constant saturation magnetic flux density of 1.2–1.3 T and coercivity of 67–74 A/m were observed. The results of this study indicated the high compatibility of the developed electrodeposition process for Ni–Fe alloys with complicated shape forming.
