Bimetal Silver Contacts
Products Description
In the current control process of industrial electrical systems, Bimetal Silver Contacts are key components for achieving the dual goals of "efficient conduction" and "structural reliability." Through a special composite process, they combine the excellent conductivity of high-purity silver with the strong mechanical support properties of the base metal, creating a functional division of labor: "silver layer conduction + base support." Whether used in motor control contactors with frequent starts and stops or in power distribution equipment with long-term operation, bimetallic silver contacts, with their stable contact performance and wear resistance, are the preferred contact option for global industrial buyers and engineering clients, providing a core guarantee for safe operation throughout the equipment's lifecycle.
Product Properties and Features
Composite Structure: Silver or silver alloys are used as the surface layer, combined with copper or other base materials to form a bimetallic layer, ensuring both electrical performance and mechanical strength.
Excellent Conductivity: Silver and its alloys have extremely low resistivity, ensuring efficient conductivity when conducting and disconnecting current.
Strong Welding Resistance: The AgSnO2 Contacts are unlikely to fuse or adhere under arc shock, ensuring circuit stability and safety.
Wear Resistance: The surface silver material has been optimized for improved friction and corrosion resistance, extending its service life.
Multi-Process Compatibility: The Silver Rivet Contacts can be combined with other components through riveting, welding, cold pressing, and other methods to accommodate various structural designs.
Customization: We can provide various silver layer thicknesses, Composite contact sizes, and base materials to meet diverse application scenarios.
Manufacturing Advantages
Precision Composite Process
Using high-precision rolling, hot pressing, or diffusion welding processes, we achieve a secure bond between the silver layer and the base metal, eliminating the risk of delamination and peeling.
Automated Production Line
Equipped with fully automated stamping, riveting, and testing equipment, we achieve efficient, high-volume, and stable production, ensuring Cold former Contact consistent product quality from batch to batch.
Strict Quality Control
Multiple tests are performed throughout the production process, including material composition analysis, silver layer thickness testing, conductivity testing, and arc resistance testing, ensuring that every Moving Silver Contact delivered to customers meets international standards.
R&D and Customization Capabilities
Our professional R&D team can develop customized bimetallic contact solutions based on customers' diverse electrical configurations and operating environments, shortening R&D cycles and accelerating product launch.
Material Advantages
| High-Purity Silver/Silver Alloy | Utilizes high-purity silver (Ag) or alloys such as silver nickel (AgNi), silver tin oxide (AgSnO₂), and silver cadmium oxide (AgCdO) as the working surface, ensuring superior electrical performance. |
| High-Quality Base Material | The base material is typically made of copper or a copper alloy, offering excellent thermal conductivity and mechanical properties, making the overall AgNi Contact more robust and durable. |
