Products Description
Composite Contacts are electrical contact components manufactured from high-performance composite materials, composed of silver alloy and pure copper, which can effectively improve the overall performance of the contacts. These contacts are usually composed of a conductive layer, a wear-resistant layer and other functional layers, forming multi-functional contact components with excellent electrical conductivity, corrosion resistance, high temperature resistance and wear resistance.
The main feature of Contactor Contacts is that they can provide more optimized electrical contact solutions through rational material combination and structural design according to different application requirements. Our Custom Electrical Contacts products, adopting advanced material technologies and processing methods, deliver high-quality solutions to help customers enhance the reliability and performance of electrical equipment.
Material Advantages
Adaptable to Diverse Load Scenarios
The surface layer of Silver Contact Points adopts dedicated silver alloys including silver-tungsten, silver-tin oxide, and silver-nickel, enabling precise matching according to load types. It achieves high electrical conductivity, arc ablation resistance, and wear resistance simultaneously, thoroughly solving the pain point that single-material contacts cannot combine conductivity and wear resistance. The silver alloy features uniform composition and low impurity content. Optimized via special processes, it maintains stable contact resistance for a long term, avoids the attenuation of electrical contact performance caused by material fluctuations, and is suitable for medium-to-high load and high-frequency start-stop scenarios.
Balanced Thermal Conductivity and Structural Strength
The base layer of Oxidized Electrical Contact is made of high-purity copper, which has excellent thermal conductivity and electrical conductivity. It can quickly dissipate arc heat generated during contact switching, reduce contact temperature rise, prevent local overheating and burnout, and extend the service life of contacts. Copper boasts outstanding ductility, compatible with precision composite forming processes to achieve tight bonding with silver alloys. Meanwhile, it provides stable mechanical support for contacts, enhances overall rigidity, and adapts to strong-vibration and complex industrial working conditions.
Optimized Performance and Cost
Strict control is applied to the material compatibility between silver alloy and copper. Verified through repeated process tests, the two materials are tightly bonded without delamination. This not only exerts the electrical contact advantages of silver alloys but also optimizes costs relying on copper, delivering far higher cost-performance than pure silver contacts. Both materials are sourced from qualified large manufacturers and undergo strict incoming inspection. They feature uniform composition, free of pores and inclusions, ensuring the structural reliability and electrical contact stability of Contact Points from the source and reducing the risk of complete machine failure for customers.
Compliant with Export-Grade Quality Requirements
Both silver alloy and copper meet international environmental standards with no harmful impurities, satisfying authoritative international certifications such as CE, UL, and CCC. They apply to global export-grade electrical equipment, helping customers expand overseas markets. The materials feature good solderability and rivetability, perfectly matching the automated assembly process of Bimetallic Contacts without affecting customers' production efficiency. They also have excellent oxidation and sulfuration resistance, adapting to complex working environments.
Application Scenarios
Industrial Control Sector
Suitable for contactors, intermediate relays, time relays, PLC output modules, industrial control cabinets, and other equipment, used in motor control, production line control, power distribution, and other scenarios. The high wear resistance and arc resistance of Bi-metal Electrical Contacts ensure long-term stable operation of industrial equipment under high-frequency start-stop and strong vibration environments, reducing maintenance costs.
Automotive Electronics Sector
Composite Electrical Contacts are used in automotive electrical components such as automotive relays, vehicle-mounted switches, headlight control, seat control, battery management systems, and charging control circuits. Adaptable to harsh vehicle-mounted conditions including high and low temperatures, strong vibration, and humidity, they feature oxidation resistance, sulfidation resistance, and a robust structure, ensuring reliable operation of on-board equipment.
Low-Voltage Electrical Appliances Sector
Used in low-voltage electrical appliances such as circuit breakers, air switches, push-button switches, thermostats, and overload protectors, undertaking circuit switching and protection functions. The low contact resistance and low temperature rise characteristics of Composite Contact Points improve the safety and service life of low-voltage electrical appliances, meeting the power distribution needs of households, commercial buildings, and industrial plants.
Customization and Services
In accordance with customers' load types, working environments and performance requirements, customization is available for the surface silver alloy material and thickness, as well as the purity and thickness of the underlying pure copper for Composite Contact Rivets. Through rational material matching, the conductivity, wear resistance and cost control of the contacts are optimized to achieve the optimal balance between performance and cost. Meanwhile, special surface treatments can be customized to enhance the anti-sulfurization and anti-oxidation capabilities of the contacts, adapting to special working conditions such as humidity and corrosion.
