Have you heard about the future development of copper-chromium alloy contacts?

    The field of electrical contact materials has entered a period of stable development. The development of traditional electrical contact materials has limited indoor space, but new industries such as new energy electric vehicles, urban rail, and solar power generation have clearly put forward new ideas for electrical contact materials. regulations, resulting in new materials. It is estimated that the technical and commercial development of high-quality silver-cadmium alloy contact materials in the future can be summarized as "one main line, two keys".

    "One main line" means that the development of new electrical contact materials should closely follow the main development line of "continuously improving economics". From the original pure Ag material to various Ag aluminum alloys, and then to the composite material of Ag alloy and Cu, the electrical contact material has been continuously improving the characteristics of precision copper alloy contact materials, reducing the volume of electrical contacts, reducing The azimuthal development of Ag usage. The reduction in the price of electrical contact materials promotes the process of electrification in various fields of social development, and promotes the continuous expansion of the sales market for electrical contact materials. With the promotion and mutual cooperation of household appliance manufacturers, the design of new electrical contacts will be further miniaturized in the future, and the production technology will pursue perfection, simplicity, efficiency and stability. High-efficiency grinding, forming, calcining, extrusion, compounding, segmentation, welding technology and related facilities will continue to occur, the intelligent level of production lines will continue to improve, and the consistency and reliability of electrical contact materials will also be improved. . The amount of Ag used in the composition design of the new high-quality silver-nickel alloy contact material must be the key consideration, and a large amount of cheap metal materials or chemical substances may be used to replace the Ag in the electrical contact material. For example, the "low-silver surface gradient oriented AgCuO electrical contact material" scientifically researched by Shenzhen University, the Ag content has been reduced to 50%; the "Cu/SnO2 circuit breaker material" scientific research day of Xi'an University of Technology, Hebei University of Technology The "Inclusion SnO2-Al?O, /Cu new nanotechnology composite electrical contact material" country also tried to use Cu to replace Ag. Continuing to control costs and improve the economics of new electrical contact materials will continue to expand in the future.
