Abstract: The CuW electrical contact material has high density, low expansion coefficient, and good electric and thermal conductivity, and so it has been widely used in switching device field. This paper briefly reviews the development history of CuW electrical contact materials. The preparation technology and modification of CuW electrical contact materials in China and abroad are summarized. The advantages and disadvantages, and application condition of different preparation technologies are analyzed. Finally, the paper points out the development direction of CuW electrical contact materials, which is expected to be a reference for the development of CuW materials.
