Products Description

Silver Cadmium Contacts are electrical contacts made from a silver-cadmium alloy, valued for their high electrical conductivity and strong arc-extinguishing ability, which enables reliable performance in high-current switching applications. Silver Contact Rivet offers good thermal stability and corrosion resistance, suitable for harsh industrial environments. However, due to environmental regulations restricting cadmium use, it is being replaced by eco-friendly alternatives. As a foreign trade company, we provide both these contacts and substitute solutions, ensuring quality compliance, global supply chain efficiency, and technical support for diverse customer needs.

Silver Cadmium Contacts

Product Advantages

Exceptional Electrical and Thermal Conductivity

Silver Contact rivets can be processed using various fabrication methods, including powder metallurgy, sintering, and thin-film deposition, to create complex contact geometries. This flexibility supports the production of ultra-thin contacts (down to sub-millimeter thicknesses) for microelectronics, as well as large-scale components for power grids. Its workability also facilitates integration with other materials in multi-layered contact assemblies, enhancing design versatility.

Outstanding Arc Erosion and Welding Resistance

The Silver Point Contact particles within the silver matrix act as a barrier against arc-induced erosion. When an electrical arc forms during contact make/break cycles, the particles suppress excessive melting of the silver, reducing material loss and surface degradation. This resistance to erosion extends the service life of contacts, even in high-frequency switching applications like relays or circuit breakers.

Mechanical Durability and Wear Resistance

The hard particles reinforce the silver matrix, enhancing the material's overall hardness and abrasion resistance. This mechanical robustness allows its contacts to withstand repeated mechanical stress from switching operations without deforming or developing surface defects. In industries like aerospace or rail transport, where vibrations and harsh environments are common, this durability ensures consistent performance and reduces maintenance needs.

Environmental Friendliness and Regulatory Compliance

Unlike traditional Contact Points, it aligns with global environmental standards that restrict hazardous materials. This eco-friendly composition eliminates health risks associated with cadmium exposure during manufacturing and disposal, making it ideal for applications in consumer electronics, medical devices, and green energy systems.
