    In this study, a powder mixture consisting of TiC (titanium carbide) and WC (tungsten carbide) reinforced AlCuNiFeCr was produced using the hot pressing technique. The AlCuNiFeCr powder mixture, TiC and WC were added at a rate of 5%, 10% and 15%, respectively. In order to produce and control to produce parameters have been produced having automation systems type of laboratory a hot pressing machine. Graphite moulds were used in production and sintering processes were carried out in a protective argon gas atmosphere. Composites were produced at a sintering temperature of 900 oC and under a pressure 35 MPa and for 4 minutes. To understand the microstructure and mechanical properties of produced specimens, their SEM and EDS analysis, XRD analysis, fracture surface SEM images, SEM mapping of elemental distribution and EDX spectrums, hardness, three-point bending, and corrosion tests were investigated. As a result, the best sample has been identified that belong to AlCuNiFeCr- 15% WC with great features.
