Silver Contact
Product Series Introduction
1. Riveted Bimetal Contact
These contacts utilize silver alloy materials such as Pure Silver (99.99%), Fine Silver (AgNi0.15), AgCdO, AgSnO₂, AgSnO₂In₂O₃, AgCu, and AgCe, combined with a red copper base. An automated riveting process achieves a secure bond and excellent electrical conductivity. Available styles include:
Solid Ag Rivets / Solid Cu Rivets
Bimetal Contacts / Trimetal Contacts
Ag Plated Contacts / Au Plated Contacts / Nickel Plated Contacts
Special sizes or contact hats for electricity meter latching relays
Product Features:
High riveting strength, no loose connections or delamination;
Customizable silver layer thickness;
Suitable for relays, contactors, and low-voltage circuit breakers;
Excellent resistance to welding and arc erosion.
2. Stamped & Riveted Copper Assembly
Using highly conductive copper (C1100/T2) stamped and formed, then riveted or welded to silver contacts, this assembly offers a lightweight yet mechanically strong design.
Features and Advantages:
Integrated stamping and riveting process, short conductive paths and low impedance;
Suitable for socket terminals, meter terminals, fuse holders, and relay contact arms;
Surface plating available (no plating or silver/gold/nickel plating).
3. Flat Silver Weld Contact
Made from materials such as AgNi, AgSnO₂, and AgCuO, these contacts are bonded to a copper substrate via resistance welding or brazing, resulting in high flatness and a strong weld.
Advantages:
Stable conductivity and low resistance;
High weld strength and long life;
Suitable for high-current devices and EV systems.
4. Machined & Welded Copper Contact Assembly
Complex structures are formed through CNC machining and then welded to silver contacts, making them suitable for high-current, high-power devices.
Features:
High precision (+-0.03°);
Uniform welding and excellent thermal conductivity;
Meets switching requirements of >500A;
Commonly used in new energy contactors, energy storage system circuit breakers, and intelligent power distribution devices.
