Products Description
Electrical Silver Bimetal Contact Rivets are not simply metal splices, but rather structurally designed based on functional layering and load-sharing logic:
Contact Working Layer (Silver Alloy): Directly participates in the switching of current and arcing, undertaking the core tasks of conductivity, resistance to welding, and resistance to ablation.
Structure and Conducting Substrate (Copper): Responsible for current conduction, mechanical fixation, heat dissipation, and welding or riveting connections to the parent component.
This clearly defined upper and lower functionalities, with each material fulfilling its specific role, ensures that the contacts maintain stable electrical performance and structural integrity under complex electrical conditions, making them particularly suitable for applications with high requirements for reliability and repetitive operation life.
Manufacturing Excellence: Superior contacts stem from absolute control over the entire production chain
Vacuum Melting of Materials
The silver alloy layer is melted in a vacuum furnace, with strict control over impurity content to prevent arc instability caused by oxide inclusions.
01
Composite Wire Drawing
Cold-extruded composite wire is used as raw material, ensuring preliminary bonding of the silver-copper interface before forming.
02
High-Speed Precision Cold Heading
Multi-station fully automated cold heading machines are used for one-time forming, ensuring dimensional consistency and morphological accuracy (e.g., spherical radius, flatness, etc.).
03
Automated Annealing
For orders with specific hardness requirements, controlled atmosphere annealing is performed to eliminate residual stress and optimize Switch Electrical Contact conductivity.
04
Ultrasonic Cleaning and Polishing
Thoroughly removes surface oil and burrs, ensuring no contamination is introduced during precision relay assembly.
05
Material Advantages: Selected for Extreme Conditions
AgNi (Silver-Ni) Base: Offers an excellent balance of conductivity and wear resistance, suitable for resistive or slightly inductive loads.
AgSnO2 (Silver-Tin Oxide) Base: A modern, environmentally friendly choice, possessing extremely high thermal stability and resistance to soldering, particularly suitable for handling large surge currents.
Copper Substrate: Extremely high thermal conductivity rapidly conducts the high temperature generated by the electric arc to the Leaf Spring Electrical Contacts, spring support, preventing localized overheating of the contact surface.
Application Advantages: Wide Coverage of Industrial Scenarios
Relays and Contactors
As core components in the control field, bimetallic rivets perfectly balance the mechanical and electrical life requirements under frequent operation, making them the preferred solution for relay and contactor Silver Contact Rivets With Silver Layers.
Wall Switches and Sockets
In the field of household appliances, although the current is relatively small, the safety requirements are extremely high. Bimetallic rivets provide stable contact connections, and their cost is suitable for the large-scale civilian market.
Timers and Microswitches
In these space-constrained, frequently operating miniature devices, the miniaturized design and high reliability of bimetallic rivets play a crucial role.
Automotive Electrical Systems
In automotive relays, horns, air conditioning switches, and other components, Silver Alloy Electrical Contacts have withstood the harsh tests of automotive vibration and temperature changes, ensuring the stable operation of the vehicle's electronic systems.
