In this study, microstructure, hardness and corrosion properties of AA2024 and AA7075 aluminum based composite materials reinforced with 5% SiC were investigated. The composite materials were produced by hot isostatic pressing method. Two different composite materials were obtained by using hot isostatic pressing method after blending in a three-axis mixer by using 5% SiC particle reinforcement to AA2024 and AA7075 alloy powders in the production of materials using powder metallurgy method. Hot isostatic pressing processes were carried out at 410 °C and 45 MPa pressure. Microstructure, density, hardness and corrosion properties of the composites were investigated. In microstructure studies, it was observed that SiC particles showed homogeneous distribution in the matrix, and in hardness studies, AA7075 aluminum alloy-based composite material had higher hardness and therefore mechanical strength. However, the corrosion resistance of this composite material in salt water environment is determined to be lower than AA2024 aluminum alloy composite material.
