Product introduction
The silver graphite material produced by the extrusion method is denser due to hot extrusion, and the graphite particles are distributed in a fibrous shape, resulting in better electrical performance. The silver graphite material produced by the extrusion method is denser due to hot extrusion, and the graphite particles are distributed in a fibrous shape, resulting in better electrical performance. Compared with the usual vertical silver pattern material structure, the parallel structure of silver graphite material not only changes the structure of the material, but also, changes the movement of electrons in the current, and the processing method of parallel structured silver graphite material is different from that of ordinary vertical structured silver graphite material. In the production and preparation of large-sized silver graphite contacts, it can obtain a denser silver graphite material than ordinary vertical structured silver graphite material, which has excellent lubrication and can greatly improve the oxidation resistance and welding resistance of silver, And the resistance to melting and welding increases with the increase of graphite content. Generally used as static contacts, it is paired with materials such as Cu, AgNi, AgW, AgWC, etc., and applied in miniature circuit breakers (MCBs), molded case circuit breakers (MCCBs), frame circuit breakers, off or motor start switches, etc.
