Abstract In various automotive and aerospace applications, aluminum alloy is prefre for its high strength and low weight. It is generally recognized that when strengthened by ceramic material, aluminum generates better mechanical properties. In various engineering applications, Al-Cu-Mg alloy is used. It can not be used in construction applications because of such limitations of decreased strength and compressibility. Silicon and 1% alumina have been used in this analysis to enhance this alloy framework. In order to study the alloy 's impact, the composition of copper and silicon was different. It was made of powder metallurgy—this composite. Copper was applied to silicon at 3.5% and 5.5% to silicon at 0.5, 1.5, and 3%. By applying 90 kN of load on the universal measuring tool, the metal powder was uniformly blended and compacted. Each of these preforms was sintered under the nitrogen atmosphere at 530 °C for 50 min, and no oxidation occurred. The desity calculation done by the sintered and green performs. The composite preforms were measured in their hardness and compressive strength.
