1 basic situation, the domestic industry(1) the development of Chinese electric power industry, increase the demand for electrical contact materialsElectrical contact materials are key functional materials, electrical alloy used in high and low pressure switch contact, and its performance directly affects the power generation equipment and the technical level of power transmission and transformation equipment. Silver based electric contact and copper base electric contact is generally applied to all kinds of low-voltage electrical appliances, is the core of low voltage electrical components, widely used in power distribution system, household appliances, transport and control of mechanical equipment. The market capacity of low voltage electrical appliances industry is closely related to the development of Chinese electric power industry. Currently, the development of our country electric power enterprise is mainly manifested in two aspects of the smart grid construction and retrofit.
(2) special copper base alloy electrical contact material can replace the traditional silver based electric contact materials bring opportunitiesRelevant report: Beijing PWC has ce information consulting co., LTD. "in 2019-2025 electrical contact materials industry pattern of supply and demand and investment outlook report"Electrical contact materials of traditional raw materials for silver, but silver smaller global reserves. In recent years, silver prices appear larger fluctuation, raw materials procurement, production cycle of the enterprise, supply capacity, debt collection. Governments and research institutions are now under the premise that does not affect the performance of the product, silver generation section of electrical contact materials technology development. At present, in the part of low voltage electrical appliances, such as circuit breakers, air switch, ac contactor, already can use copper base special alloy electrical contact materials to replace the traditional silver based electric contact material, giving special copper base alloy electrical contact materials development has brought great opportunities.
