Products Description
Silver Finish Metal Buttons are square, sheet-shaped electrical contact elements with a silver-based composite material as the working surface, bonded to a copper or steel substrate through precision welding or brazing. They are primarily used in new energy power electronic equipment, low-voltage electrical switches, and relay systems to perform current conduction and interruption functions. This product leverages the high conductivity and oxidation resistance of the silver layer, combined with the structural strength of the substrate material, to achieve low contact resistance, high resistance to arc erosion, and long-life stable operation under high voltage, high current, and frequent operating conditions.
Material Advantages and Process Control
Silver-Based Composite Material Selection
Pure silver, silver alloys, or Silver Cadmium Oxide Contacts are selected based on the application scenario to balance conductivity and arc resistance.
Composite Welding Technology
The Silver Contact Welding process is used to achieve a metallurgical bond between the silver layer and the substrate, avoiding incomplete soldering or embrittlement of the heat-affected zone.
Production Process and Quality System
Multi-process Integration
Based on core processes such as metal cold heading, stamping, Composite Welding Contact, and electroplating, full-process control is achieved from raw materials to finished products.
Standardized Operating Procedures
Standardized operating instructions are used for key aspects such as mold design, stamping, welding parameters, and electroplating time to ensure batch-to-batch consistency of Brazed Contacts on Terminal.
Inspection and Testing
Equipped with coordinate measuring machines, spectrometers, contact resistance testers, and other equipment, full inspection of the dimensional accuracy, material composition, and electrical properties of Welding Button Contacts is conducted, complying with ISO9001-2015 and IATF16949 standards.
Application Advantages
| Photovoltaic Inverters | In photovoltaic inverters, high-frequency switching contacts must withstand the high temperatures and energy impacts of DC arcs for extended periods. By employing a Silver Joint Contacts design, the silver-based composite material forms a metallurgical bond with the substrate, significantly improving the contacts' resistance to arc erosion and high-temperature performance. |
| Energy Storage Systems | The charging and discharging processes of energy storage systems involve large current switching, requiring contacts with high conductivity, low contact resistance, and anti-welding properties. Through Contact Assembly Welding technology, the silver-plated contacts are reliably connected to the contactor substrate, preventing contact failures caused by poor soldering or thermal stress. |
| Electric Vehicle Charging Stations | Electric vehicle charging station contacts must withstand frequent plugging and unplugging operations and high power transmission, placing stringent requirements on wear resistance and conductivity stability. Based on the Silver Bonded Contact Components design, the molecular-level bonding between the silver layer and the substrate enhances the surface hardness and wear resistance of the contacts, reducing plating peeling or increased contact resistance due to friction. |
