Bimetal Silver Contact Point

Bimetal Silver Contact Point is a riveted electrical contact element made of a copper substrate and a silver-based alloy contact through a precision composite process. It is widely used in relays, microswitches, circuit breakers, and various low-voltage electrical appliances as a core actuator for current switching. This product metallurgically combines highly conductive copper with an arc-resistant silver alloy, ensuring excellent conductivity while significantly improving the contact's wear resistance and weld resistance under frequent switching conditions.

Products Description

In electrical control systems, the reliability of the contacts directly determines the lifespan and safety of the entire device. Bimetal Silver Contact Point employs advanced bimetallic composite technology, achieving atomic-level bonding between the silver alloy contact and the copper substrate through cold forging, forming an integrated structure. Compared to traditional single-piece contacts or welded contacts, the bimetallic structure offers significant advantages in material utilization, conductivity consistency, and long-term stability.

Our Silver Copper Composite Rivet Contact is suitable for various applications with rated currents ranging from milliamperes to tens of amperes, covering industrial control relays, automotive relays, home appliance switches, smart meters, and new energy power distribution equipment.

Material Advantages

High-Purity Raw Materials

We source all raw materials exclusively from internationally recognized suppliers. Each batch is accompanied by a corresponding material certificate, guaranteeing full compositional traceability and strict conformity to global standards. This ensures low impurity levels and consistent material properties, establishing a dependable foundation for our Bi-Metal Silver Alloy Contacts.

Complementary Composite Structure Performance

By pairing the copper base's high electrical and thermal conductivity with the silver alloy layer's inherent resistance to arcing and welding, we achieve a synergy that maximizes contact performance. This approach dramatically lowers silver consumption, offering a cost-effective solution without compromising on reliability.
