Products Description
As one of China's few manufacturers mastering tri-metal composite technology, we present Electric Double Metal Contact Rivets-engineered with silver alloy (head/foot) and oxygen-free copper core for superior conductivity, wear resistance, and cost efficiency. Ideal for high-frequency switching applications like industrial control relays and automotive connectors, our contacts deliver precision performance at a fraction of the cost of solid silver alternatives.
Technical Highlights
Substantial Cost Reduction
Our AgCuAg Trimetal Contacts offer a more economical alternative to pure silver contacts. By using silver alloy only at the head and foot, and purple copper in the middle, we significantly reduce material costs while maintaining excellent electrical conductivity and contact performance.
Precise Layer Thickness and Strong Bonding
We ensure precise control over the thickness of the silver layers at the head and foot, as well as strong bonding between the layers. This guarantees that the silver layers will not peel off or leak, ensuring long-term reliability and stable electrical connections for your Trimetal Moving Contacts.
Perfect for Industrial Control Relays
These Electric Double Metal Contact Rivets are specifically designed for applications such as industrial control relays that require moving contacts with switching functions. The unique multi-layer structure and material combination make them capable of withstanding the mechanical and electrical demands of industrial environments, providing reliable performance for relay operations.
Ideal Applications: Where Movement Demands Durability
Perfect for tri-metal moving contacts in high-reliability systems:
(1). Industrial Relays: AC contactors (e.g., ABB, Schneider compatible), motor control units, and circuit breakers.
(2). Automotive Electronics: 12V/24V automotive relays (IATF 16949-approved), ECU connectors, and start-stop systems.
(3). Smart Grid Equipment: Prepaid meter switches, power distribution relays, and renewable energy inverters.
| Feature | Solid Silver Contacts | AgCuAg Trimetal Contacts |
| Contact Resistance | ≤3mΩ | ≤3mΩ |
| Wear Life (Cycles) | 80,000+ | 100,000+ |
Our Trimetal Silver Contacts are widely used in industrial control relays and other electrical equipment requiring moving contacts with switching functions. They are particularly suitable for applications where cost-effectiveness and reliability are crucial, such as in manufacturing, automation, and electrical control systems.
