Powder metallurgy (PM) provides an efficient method for producing complex metallic components through controlled compaction and sintering. This study examines electrolytic iron powder with zinc stearate (ZnSt) as a lubricant to evaluate the influence of processing parameters on densification and mechanical performance. The experimental variables included compaction load (400, 450, and 500 kN), lubricant content (0%, 1%, and 2%), and particle size ranges (250–300 mesh and 300–350 mesh). Pre-sintering was conducted at 600 °C, and microstructural characterization was carried out using scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). Powders with a mesh size of 300–350 and crushed at 500 kN had the highest density. At 500 kN, the density increased by 18%. The optimum combination of the parameters 300–350 mesh particle size, 2% lubricant, and 500N load was determined to have an optimal density (ρ) of 6.812 g/cm3.
