NiCoCr thin films were electroplated for different current density. FCC structured crystals were observed in XRD study. Coercive force and magnetization value exhibits soft magnetic nature. Electroplated NiCoCr films with electrolytic current density (2, 3, 4 and 5 mil.Amp/cm²) shows uniform deposition on the substrate. Cobalt composition was minimum as 21.31 wt% for current density 5 mA/cm².  The consistence of chromium and nickel increased while current density was improved. Thin films deposition with high current density shows low hysteresis loss and soft magnetic nature.The hardness of deposits increases when current density is increased.
