Abstract
Based on the typical demand for advanced copper alloys by emerging industries and major engineering projects, such as electrical engineering, electronics, 5G communications, new energy vehicles, aerospace, and rail transit, this study systematically summaries the current status of international and domestic copper alloy industries, including high-strength and high-conductivity copper alloy, wear and corrosion resistance copper alloy, elastic copper alloy with ultra-high strength, advanced copper matrix composites, and copper alloy wires and foils with high precision. The typical market demand of the advanced copper alloys is analyzed and the medium and long-term development goals and key technologies of the copper alloy materials in China are proposed. Moreover, industrial development suggestions are also proposed including promotion of the overall planning and integrated development of production, research, application, and management; enhancement of equipment development, technology development, and market expansion abilities; improvement in the research and formulation of product standards; and establishment of a training system for young scientists and technicians. This study is expected to promote the green, high-end, and intelligent development of advanced copper alloy materials in China through the improvement in independent innovation system regarding the copper alloy materials, equipment, technology, and industrialization, thus to meet the demands of national economy and national defense construction.
