Fe-Cu is known as a metastable and immiscible alloy. Therefore, many problems are encounteredin the production of Fe-Cu alloys by conventional casting. Researchers have used differenttechniques for the production of successful Fe-Cu alloys. For this reason, in this experimentalstudy, the production of pure Fe and Fe-Cu (10%, 20% and 50% by volume) alloy compacts wasinvestigated by spark plasma sintering, a powder metallurgy technique. The effects of Cuaddition at different volume ratios on microstructure, density, hardness, three-point bending,wear and electrical conductivity were investigated. It has been determined that themicrostructures in Fe-Cu alloys consist of α-Fe and ε-Cu phases. Compared to the pure-Fesample, improvements were determined in the density, mechanical properties and electricalconductivity of the Fe-Cu alloy samples produced with the addition of Cu at 10%, 20% and 50%volume ratios. When the Fe-Cu alloys were compared with each other, the highest density,hardness, bending stress at break and the lowest wear rate were determined in the Fe-Cu alloycontaining 20% volume ratio Cu. The addition of Cu to Fe at 50% volume ratio caused adecrease in the density, mechanical properties and electrical conductivity.
