Abstract: The study investigated the effects of trace additions of iron on grain characteristics, electrical conductivity, and mechanical properties of tin bronze. The experimental alloys were produced with chromium concentrations of 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and 1.0% by weight using the permanent mold casting technique. Hardness, tensile, and impact strength tests were performed on the cast samples. Microstructures of the specimens were also analyzed using optical microscopy. Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) were used to characterize the cast specimens. The results indicated that iron to Cu-10wt%Sn alloy refined and modified the alloy's structure, improving the experimental alloy's tensile strength and hardness by 43.6%, and 37.1% respectively at 0.8wt% Fe content. The addition of iron led to the formation of the intermetallic phase which further contributed to the increase in tensile strength and hardness of the alloy.
