This paper presents a comprehensive investigation into the microstructure and mechanical properties of aluminum 7068 reinforced with channa husk ash and silicon carbide through the application of powder metallurgy. The aluminum 7068, silicon carbide, and channa husk ash were utilized in powdered form, with their sizes tailored to meet the required specifications. These powders were then mixed together in varying proportions and compacted under a pressure of 400MPa using a hydraulic press to fabricate samples. Subsequently, the samples were subjected to a sintering process at a temperature of 600°C for a duration of 2 hours. The resulting samples were evaluated for density, compressive strength, hardness, and their microstructure was examined using a scanning electron microscope. Additionally, an energy dispersive x-ray analysis was conducted to confirm the presence of silicon carbide and channa husk ash within the aluminum matrix.
