Current Situation and Development Trend of Electrical Contact Materials for Organic Temperature Fuses

This paper introduces the basic principle of organic temperature fuse and the requirements of sliding contact for electrical contact materials, as well as the material types, preparation processes, material performance, and characteristics of electrical contact materials currently used in this field. And compared and analyzed the advantages and disadvantages of electrical contact materials made by solid solution strengthening mechanism and dispersion strengthening mechanism used as sliding contact in the field of organic temperature fuse, and briefly explained the development trend of reducing the use of precious metals of sliding contact materials, as well as the feasibility of improving the breaking capacity of fuses in pairing forms.
