In this study, it was aimed to investigate the microstructure and corrosion properties of C95200 and C95300 aluminium bronzes. C95200 and C95300 alloys are produced as cast in aluminium bronze norms. Microstructure and corrosion samples were formed from the produced aluminium bronze ingots.Optical microscope, SEM and EDS investigations were done. Corrosion test was performed on the alloys in 3,5% NaCl environment for 72 hours. In addition, potentiodynamic polarization corrosion test was performed. In microstructural studies, black areas represent primary α structure, white areas at grain boundaries represent secondary phase (β). In the potentiodynamic polarization corrosion test, it was determined that the corrosion resistance of the C95200 alloy was higher than the C95300. This was also observed in the immersion corrosion test.
