Electrical Contact Riveted Brass
Products Description
Electrical Contact Riveted Brass (silver contact brass riveted assembly) is a high-performance composite structural component used for electrical connection and conduction control, widely applied in relays, contactors, switches, motor protectors, and new energy electrical control systems. This assembly consists of highly conductive silver-based contacts firmly bonded to a mechanically superior brass substrate using a precision riveting process. It combines excellent conductivity, wear resistance, and structural strength, making it an indispensable key component in low-voltage electrical appliances and new energy electrical control products.
The combined design of the silver contacts and brass substrate ensures stable conduction and long lifespan performance under high-frequency switching, high-current surges, and complex operating conditions. Compared to traditional welded or single-metal components, the riveted silver contact structure offers significant advantages in cost control, reliability, and production consistency.
Structure and Features
Silver Contact Layer – Made of high-purity silver or silver alloys (AgNi, AgCdO, AgSnO₂, etc.) to ensure excellent conductivity and arc resistance.
Brass Substrate – Utilizing a high-strength CuZn alloy material, providing excellent mechanical support and fatigue resistance.
Riveting Zone – Achieving a high-strength metal bond through cold or hot riveting processes, ensuring a seamless and secure connection between the In-Die Rivet Electrical Contacts and the substrate.
The assembly's appearance can be customized to meet various application requirements, including different shapes (circular, rectangular, irregular shapes) and mounting methods (single-sided riveting, double-sided riveting, multi-layer structures), satisfying the current load and space layout requirements of different devices.
Product Advantages
| Excellent Mechanical Stability | Brass, with its moderate hardness and excellent ductility, maintains stable geometry and connection strength even in environments subject to repeated switching and high-frequency vibration, reducing the risk of contact loosening and mechanical fatigue. |
| Highly Reliable Riveting Process | Precision stamping and automated riveting equipment ensure the bond strength and positioning accuracy between the Contact Riveted Components and the brass base. The entire riveting process is performed under constant pressure and precise temperature control, ensuring crack-free, peeling-free, and weld slag-free joints. |
| Optimized Cost-Effectiveness | Compared to monolithic silver components or welding processes, the riveted composite structure significantly reduces precious metal usage, reducing unit cost while maintaining electrical performance. It is suitable for both mass production and OEM customization. |
| Customizable Designs and Diverse Specifications | We can customize the shape, thickness, rivet point location, and Electrical Spring Contacts material type (AgNi, AgSnO₂, AgCu, AgCdO, etc.) based on customer design drawings or technical specifications. A variety of riveting styles (solid rivet, bimetal rivet, tri-metal rivet) are available to meet different current requirements. |
Manufacturing and Process Advantages
Precision Stamping and Automated Assembly
Xiamen Apollo utilizes high-speed stamping lines and fully automatic riveting machines to automate the entire brass sheet process, from uncoiling, stamping, polishing, riveting, to testing. Brass Stamping Terminal dimensional tolerances are controlled to ±0.01mm, ensuring consistency and high efficiency in mass production.
Strict Surface Treatment and Quality Control
The brass substrate undergoes degreasing, pickling, electroplating, or anti-oxidation treatment to effectively enhance corrosion resistance and weld compatibility. All Switch Parts riveted with Silver contacts undergo visual inspection, resistance testing, pull-off strength testing, and conduction life testing before shipment to ensure the long-term reliability of each riveted component.
High-Purity Silver and Alloy Contact Manufacturing Capabilities
Electrical Contact Stampings are made from 99.99% pure electrical silver or silver alloys. Processed through cold extrusion, cutting, turning, and precision polishing, the contact surfaces are smooth and flat. A variety of arc-resistant formulations are available to balance electrical conductivity and weld resistance for different application requirements.
Strict Control of Production Environment and Traceability System
The production workshop employs a constant temperature and humidity control system to prevent oxidation or stress deformation of metal materials. Simultaneously, each batch of Silver Contact Points with brass terminals has a traceable number, enabling full recording from raw material entry to finished product delivery, facilitating customer quality audits and after-sales tracking.
