Product Profile of Bimetal Contact Rivets
Bimetal Contact Rivets
Bimetal Contact Rivets are precision-engineered fasteners that combine two different metals to provide enhanced electrical and thermal conductivity properties.
Enhanced Electrical Conductivity
The combination of metals in Bimetal Contact Rivets, such as copper and silver, provides superior electrical conductivity, ensuring efficient energy transfer.
Optimized Thermal Performance
These rivets offer excellent thermal conductivity, which is crucial for applications where heat dissipation is necessary to prevent component failure.
Thermal Expansion Compensation
The bimetallic design compensates for different thermal expansion rates of the materials, reducing stress on connections and improving reliability over a wide temperature range.
Corrosion Resistance
The use of metals like silver or nickel in the rivet construction provides inherent corrosion resistance, extending the service life of the connections.
Advantages of Using Materials
Materials key Advantages
Economical Efficiency
Bimetal Contact Rivets often have a head layer made from precious metals like silver or its alloys, which are known for their excellent electrical conductivity, while the base material is usually made from pure copper, chosen for its good formability and electrical conductivity. This design not only economizes the use of precious metals but also reduces the overall cost of the electrical contacts.
Enhanced Performance
The use of different metals allows for a balance of properties. For instance, the base metal provides strength and durability, while the contact material ensures low electrical resistance and high conductivity. This combination results in composite silver contacts that are not only cost-effective but also perform well under various conditions.
Product Features
Core Features
Composite Material Design
These Bimetal Silver Contacts are constructed with a combination of materials, typically a precious metal such as silver or its alloy for the Bimetallic Contact Rivet head and a base material like electrolytic grade copper, which provides strength and durability.
High Electrical Conductivity
The use of silver or silver alloys in the sliver contact head ensures low electrical resistance and a stable temperature rise, making them suitable for high-load, high-current environments.
Enhanced Durability
The base material of copper provides additional strength and support to the contact material, ensuring the longevity of the rivet.
Wide Range of Applications
Bimetal Contact Rivets are suitable for use in AC contactor auxiliary contacts, relays, switches, household appliances, timers, and other low-voltage appliances due to their unique material properties and performance.
Manufacturing Process Flow
| Material Preparation and Melting | Select high-purity silver and alloying elements, then melt them in a furnace to create an alloy ingot. |
| Oxidation and Crushing | Subject the ingots to high-temperature and high-pressure oxidation to form a mixed phase of silver oxides, followed by crushing the oxidized Silver Contact AgSnO2 material. |
| Extrusion and Shaping | Press the crushed Silver Contact AgSnO2 material into shape and then extrude it at high temperatures to form bars or strips. |
| Drawing and Refinement | Draw the extruded material into a wire of the desired diameter, refining the dimensions and properties. |
| Surface Treatment and Cleaning | Apply Bimetal Contact Rivets surface treatments such as electroplating to enhance conductivity and corrosion resistance, followed by thorough cleaning. |
| Quality Control and Final Inspection | Conduct a final inspection to ensure the rivets meet all performance and dimensional specifications before packaging and distribution. |
