Silver Bimetal Contact Rivets For Electrical Contactor
Products Description
Silver Bimetal Contact Rivets for Electrical Contactors are critical conductive and breaking components in low-voltage electrical appliances, industrial contactors, electromagnetic relays, circuit breakers, and switchgear. These products achieve a balance between conductivity, arc resistance, mechanical strength, and cost control by metallurgically combining high-performance silver-based contact materials with a copper or copper alloy substrate.
Core Performance Advantages
Significant Cost Optimization
By replacing most of the silver material in the intermediate layer with copper, AgCuAg Composite Rivet Contacts can reduce the amount of precious silver used by more than 50% while maintaining electrical contact performance. This cost optimization has direct purchasing value for industrial relay manufacturers using high-volume applications.
Guaranteed Reliability of Bidirectional Contact
The bidirectional silver layer design of the triple composite structure ensures that the silver alloy surface always provides electrical contact during switching operations. This feature is particularly important for industrial control scenarios requiring frequent switching, effectively preventing poor contact and premature failure caused by copper surface oxidation.
Excellent Conductivity and Heat Dissipation
The high conductivity and thermal conductivity of the copper interlayer ensure that the temperature rise of the Electrical Tri-Metal Rivet under rated load is controlled within a reasonable range, reducing the risk of relay coil aging and insulation degradation due to overheating.
Stable Contact Resistance
The low oxidation characteristics of the silver alloy contact surface, combined with the low resistance characteristics of the copper substrate, enable the Trimetal Silver Contact Rivet to maintain stable contact resistance during long-term operation, reducing control signal distortion caused by contact resistance drift.
Core Application Industries
Industrial Control Relays: Global industrial control component manufacturers and European and American automation parts manufacturers are the main purchasing groups. Trimetal Multi-Layer Riveted Contacts are primarily used in combination with switching power relays and PCB board switching relays.
Low-Voltage Electrical Components: AgCuAg Composite Rivet Contacts are widely used as moving contacts in small auxiliary contactors, temperature control switches, and sequence controllers in home appliance manufacturing and industrial equipment electrical control modules.
Automotive Electrical Components: AgCuAg Multi-Layer Electrical Contacts are used in automotive body control module switching relays and low-power automotive electrical control switches, adapting to the North American and European automotive parts supply chains.
Full-chain quality control system
Incoming material inspection
The silver alloy wire and copper substrate used in the Trimetal Silver Alloy Contacts undergo physical and chemical testing upon arrival at the factory to verify material composition and conductivity parameters.
In-process sampling inspection
The metal bonding degree is tested during the composite rolling process; dimensional tolerances of Three Compound Contacts are controlled during cold heading; and contact resistance and silver layer adhesion are sampled for finished products.
Outgoing full inspection
The continuous-off simulation life of Trimetal Silver Contacts is sampled to ensure that each batch of shipped products meets customer electrical parameter standards.
