Fixed Silver Contact
Products Description
The performance and operational lifespan of relays within electrical control and protection systems are critically dependent on the quality of their primary conductive components. Since 1990, we have been committed to providing professional electrical metal solutions to the global market. The Fixed Silver Contact represents one of our key technological offerings. Rather than utilizing a single metal composition, it is manufactured through an advanced composite process that metallurgically bonds a high-performance silver alloy working surface to a high-strength copper alloy support body. This integrated contact structure ensures superior electrical characteristics while delivering enhanced mechanical durability and improved cost efficiency-positioning it as an optimal alternative to conventional pure silver contacts.
Product Core Selling Points
High-performance materials
Utilizing advanced Nobel Metal Contacts technology, combined with high-quality alloys such as AgSnO2, ensures that the contacts maintain excellent conductivity and corrosion resistance even under extreme conditions.
Precision Manufacturing
Through the Cold Headed Electrical Contacts process, high-precision shaping of contacts is achieved, reducing subsequent processing steps and enhancing production efficiency.
Broad Applicability
As Bimetal Rivet-type Contacts, our products can perfectly fit various electrical relays and switch devices.
Product structure disassembly
The design of our contacts features a three-element architecture: the contact head, the rivet body, and the silver layer. The contact head is crafted from a high-conductivity silver alloy, selected specifically to deliver superior contact performance under demanding electrical conditions. The rivet body is shaped using Cold Forming Process Contacts technology, a precision manufacturing method that ensures consistent structural stability and robust mechanical strength. To further enhance durability, a silver layer is deposited onto the surface of the contact points, significantly improving resistance to oxidation and corrosion in challenging operating environments.
Comparative Advantage over Competitors
| Comparison Items | Our product | Common product in the market |
| Material Structure | Round Silver Bimetal Rivet features an optimized dual-metal composite structure, achieving the best balance between performance and cost. | It may be pure silver (with high cost) or single-metal silver plating (with short lifespan) |
| Advanced technology in the process | High-efficiency and high-precision cold heading forming, with consistent quality of Bimetal Silver Composite Contact Rivets. | It may adopt turning processing, which results in significant material waste and poor consistency. |
| Taking reliability into account | Metallurgical bonding. The bonding strength of the Bimetal Rivet-type Contact is extremely high, with no risk of detachment. | Electroplating combined with mechanical pressing may pose a risk of delamination. |
| Customized depth | Noble Metals Contact can be deeply customized according to the customer's electrical performance, size and assembly method. | The standard products are dominant, with low flexibility in modification. |
