Products Description

Pure Tungsten Contacts are high-purity tungsten-based electrical contact components, meticulously engineered for high-load and high-frequency switching scenarios. They serve as the core conductive parts in relays, circuit breakers, and other electrical equipment, ensuring stable current interruption and conduction.

Key Value Propositions

Solve common issues of traditional contacts, such as excessive wear and arc erosion.
Extend the service life of electrical equipment and enhance operational safety.
Ensure reliable performance under harsh working conditions, including extreme temperatures, high humidity, and intense vibrations.

Technological Edge Highlights:
Ultra-high purity tungsten material (W≥99.95%) for superior electrical and thermal properties.
Exceptional arc resistance and anti-welding capabilities, reducing contact failures.
Customizable in terms of size, shape, and surface treatment to meet specific customer requirements.

Material Science Advantages

Purity Control

Employ a combination of powder metallurgy and multiple electron beam melting processes, reducing the total impurity content to less than 0.05%. This strict purity control ensures excellent electrical conductivity and thermal stability of Pure Tungsten Contacts.

Crystal Structure Optimization

Through directional solidification technology, the grain orientation of tungsten is optimized, enhancing material density and mechanical strength. This results in better resistance to deformation and wear under high-stress conditions.

Alloying Enhancements

Optional doping with elements like rhenium (Re) and thorium (Th) can significantly improve the high-temperature mechanical properties of tungsten. These alloys maintain the Tungsten Brazed Rivet's strength and ductility even at elevated temperatures, making them suitable for extreme environments.

Raw Material Traceability

Each batch of raw materials is accompanied by a spectral analysis report, enabling full traceability of the material composition. This transparency ensures consistent quality across all Flat Tungsten Contact Points.

Structural Design Innovations

Flat Contact Precision

Flat Tungsten Contact Points feature a surface flatness tolerance of ≤5μm and a mirror-polished finish (Ra≤0.2μm). The edge chamfer design (R0.3 - R1.0mm) reduces electric field distortion, making them suitable for high-voltage applications up to 10kV or more.

Brazed Rivet Technology

Tungsten Brazed Rivets are produced with precise vacuum brazing temperature control (±5℃) to prevent tungsten grain coarsening. The rivet shank diameter tolerance is controlled within ±0.01mm, facilitating high-speed installation by automated riveting equipment.

Composite Contact Structure

Iron Tungsten Contact Rivets utilize a gradient alloy transition layer at the interface between iron and tungsten. This design minimizes the difference in thermal expansion coefficients (<10%), preventing cracking during thermal cycling. For Car Horn Tungsten Contact Rivets, the specially designed arc-shaped contact surface (R5 - R15mm) optimizes sound wave transmission and reduces contact sticking.

Customizable Geometries

Support the production of special structures such as hemispherical, cylindrical, and grooved contacts. These custom geometries can be tailored to specific electrical and mechanical requirements, enhancing Car Horn Tungsten Contact Rivet's performance in different applications.
