Abstract
AgCdO electric contact material is widely used in low voltage industries, such as contactors, electric relays, switches and miniature circuit breaker, therefore it is called “the universal material”. This material is mainly prepared by internal oxidization and it has good machining properties and ani-welding resistance. In this paper, AgCdO(12) electrical contact materials with different oxide particle sizes (0.8, 1.2, 1μm) will be prepared. Besides, the microstructure, mechanical properties and electrical properties of different AgCdO(12) materials will be investigated. It is expected to provide reference for research and design of electrical contact materials.
