This paper studies the optimization of the composition and preparation process of high-strength and high-conductivity copper alloy. By reviewing literature and experimental methods, the factors affecting the properties of high-strength and high-conductivity copper alloy are analyzed, and the preparation process is optimized by using the method of design of experiment to obtain the optimal composition and preparation conditions of high-strength and high-conductivity copper alloy. The results show that adding appropriate amounts of elements such as aluminum, iron and manganese can significantly improve the strength and conductivity of the alloy, while excessive addition will increase the brittleness of the alloy. The optimal preparation conditions are 40min of alloying time, 1050℃ of alloying temperature, and graphite crucible. In addition, the effect of different composition ratios on the alloy properties is also studied. This study provides theoretical and practical guidance for the preparation of high-strength and high-conductivity copper alloy.Keywords: high-strength and high-conductivity copper alloy, composition optimization, preparation process, electrical performance, mechanical performance.
