Abstract: As a typical bimetallic composite material, copper aluminum bimetallic gradient materials have
excellent mechanical, chemical, and physical properties. It’s characterized by the combination of the high electrical
and thermal conductivity of copper and the lightweight, easy welding, and low cost of aluminum, and are thus widely
applied in various fields. Based on the performance characteristics, this article reviews the preparation methods of
copper aluminum bimetallic gradient materials, elaborate their pros and cons, with the focus on the application of
composite processes, aiming to assist engineers in selecting appropriate preparation processes, optimizing corresponding
parameters, thereby saving costs, enhancing bonding quality and improving production efficiency.
Key words: Copper aluminum bimetallic; Gradient materials; Preparation process; Research progress
