In this study, different amounts of iron are added to nickel-aluminum bronze produced by mechanical alloying and its effects on microstructure, hardness, and wear behaviors are investigated. Four different amounts of Fe (3.5, 4, 4.5, and 5 wt%) was added to Cu10Al5Ni alloy and mechanically alloyed for 60 min. After cold pressing (600 MPa), the alloy powders were sintered at 800 degrees C and cooled in furnace to room temperature. The samples were characterized with scanning electron microscope (SEM + EDS), X-ray diffraction and hardness and density measurements. Wear tests were performed using a block-on-ring wear testing device with 0.2 m/s sliding velocity, four different sliding distances (400-1600 m) and three different loads (10 N, 20 N, and 30 N). As a result of the studies, it was found that the hardness value increased, and the density decreased with increasing Fe amount. Cu10Al5Ni containing 5% Fe was measured with the highest hardness value (55.74 HV) and the lowest density value (7.72 g/cm(3)). Also, Fe- and Ni-rich kappa intermetallic compounds were formed in the microstructure of the alloy. The wear tests showed that the alloy containing 5% Fe had the lowest weight loss and wear rate as well.
