Products Description
As key components in electrical connections and power-off control, AgNi Bimetal Contact Rivets, with their excellent conductivity, resistance to welding, and wear resistance, have become indispensable components in electrical products such as relays, contactors, and switches. We specialize in providing high-quality AgNi composite rivet solutions for high-end applications such as new energy, industrial control, rail transit, and smart grids. With superior process control and advanced equipment support, we ensure that each contact rivet delivers highly consistent performance and reliability in mass production.
Typical Applications of AgNi Bimetallic Contact Rivets
High-Performance Relays & Contactors
Automotive relays (especially high-voltage main relays for new energy vehicles), industrial control contactors, and power relays. They address welding, short life, and contact resistance drift caused by frequent switching, ensuring reliable control circuits for Bimetal rivet-type contact.
01
Medium and Low Voltage Circuit Breakers (MCBs/MCCBs)
Main and arcing Bimetal Silver Composite Contact Rivets. They improve breaking capacity, reduce contact sticking and capacity loss caused by arc erosion, and ensure precise operation of protective functions.
02
Power Switches & Transfer Switches
UPS, Power Distribution Units (PDUs), and ATS. They ensure stable switching and low losses for high currents, reduce equipment temperature rise, and improve energy efficiency for Bi-metal Silver Contacts.
03
Industrial Control and Automation Equipment
Electromagnetic starters, motor controllers, and sensors. They withstand vibration and shock, adapt to harsh industrial environments, and reduce equipment downtime for Round Silver Bimetal Rivet.
04
New Energy
Electric vehicle charging stations, battery management system (BMS) contactors, and photovoltaic inverters. Meeting high voltage, high current, and high reliability requirements is the key to safe and efficient energy control.

Raw material advantages summary table
| Material Name | Characteristics | Performance Advantages | Application Value |
| High-purity silver (Ag ≥ 99.9%) | Excellent conductivity and ductility | Low resistance, easy riveting, and oxidation resistance | Improves Electrical Contact Rivet conductivity and stability |
| Electrolytic nickel (Ni ≥ 99.5%) | High melting point, high hardness, corrosion resistance | Strong resistance to welding and excellent wear resistance | Extends service life and prevents arc sticking |
| AgNi composite layer | Bonded by rolling/diffusion welding | Strong bond and controllable layer thickness | Meets varying current carrying and mechanical requirements |
Advantages of the Composite Process: Silver-nickel metallurgical bonding for stable and reliable performance
Cold-rolled composite bonding combined with thermal diffusion welding ensures a tight bond between the silver and nickel layers, ensuring no separation or bubbles between the layers.
The silver layer thickness can be controlled from 0.1mm to 1.0mm to meet different current levels and application requirements.
Multi-stage annealing and leveling treatments are performed on the composite material to eliminate stress, improve workability, and enhance Silver Electronic Contact stability.
Multiple specifications of composite strip can be flexibly cut and stamped, supporting the development and manufacture of Electrical Silver Bimetal Contact Rivet structures with varying designs.
