Products Description
Our company has been deeply involved in the manufacturing of silver-tungsten and tungsten-copper electrical contact components since 1990. We standardize and mass-produce tungsten-copper vacuum electrical contact components, with our core product category being Tungsten Copper Vacuum Contacts. We provide customized contact solutions for power electronics applications, including new energy power transmission equipment, automotive electronic control systems, high-voltage vacuum relays, high-power contactors, and vehicle horn systems. All components are formed using a precision stamping and solid-state diffusion welding integrated process, adaptable to harsh operating conditions such as DC/AC high-voltage switching, frequent high-current switching, and continuous arc erosion. We are specifically designed to solve four core engineering pain points for system R&D engineers: contact erosion, welding, conductivity attenuation, and insufficient service life.
Product Advantages
Long-Term Breaking Reliability
The tungsten framework effectively resists arc erosion, while the copper network rapidly conducts heat, reducing structural damage caused by localized overheating. This synergistic mechanism allows the Tungsten Copper Solid Rivet Contacts type structure to maintain stable performance even after multiple operations.
Outstanding Thermal Management Capabilities
High thermal conductivity helps reduce localized temperature rise, decreases the risk of thermal fatigue crack formation, and improves reliability under continuous operation.
Stable Contact Resistance
Proper control of material ratios, sintering density, and processing precision helps reduce resistance fluctuations at the Car Horn Electrical Wolfram Tungsten Contact interface, meeting the requirements of high-performance power distribution equipment.
Strong environmental adaptability
In vacuum arc extinguishing systems, the material exhibits good resistance to welding and dimensional stability, making it suitable for frequent start-stop and impact load conditions. The material design concepts of Electric Horn Tungsten Contacts in refractory applications can also be referenced.
Product Details and Features
Precision Machining Interface
The contact surface of the Tungsten Riveting Horn Contact Point undergoes precision machining to control flatness, which helps reduce local current concentration.
