Electrical contact materials

Electrical contact materials are the important materials in electric power, electrical control circuit and leading current of electric appliance, which are used for switching and leading current. They are rivet contacts (granular), contact piece and contact profile etc.

The characteristic of electrical contact is not only affected by materials but also affected by other factors such as contact pressure and environment. All of these factors are interaction and make working condition become very complex and diverse. All of these factors require electrical contact materials to have higher capability. Contact resistance and arc erosion resistance ability are the most important factors in the electrical contact process. Customers can choose electrical contact material categories according to product applications. Beijing Sunrising Advanced Materials co, Ltd is continually engaged in researching new types of electrical contact materials and developing new processing technologies to meet different requirements of different customers.

   Silver, gold, palladium, platinum and their alloys are used for Electrical contact materials. In order to save precious metal and comprehensive utilization of different material properties, non-precious metals are used to substitute for precious metal partly to make composite contact materials.
