The laws of electrical erosion size change, contacting reliability depending on field of contact unit for devices by a voltage up to 1000 V application are established. The copper-based composite contact materials are developed application of which will allow to considerably reducing and sometimes completely excluding expenses of silver-content materials. By introduction of the special additives of some metals and their oxides in association with fibrous technology of manufacturing it was possible to achieve high corrosion resistance to aggressive gases and steam action.
