Copper-Tungsten Contact Points: The Choice for High-Performance Electrical Contact Materials

Copper-tungsten contact points, as a choice for high-performance electrical contact materials, possess significant advantages and characteristics that make them an ideal choice for numerous applications. Below are some key reasons for the preference of Copper-tungsten contacts as high-performance electrical contact materials:

Unique physical and chemical properties: Copper-tungsten contacts combine the benefits of both tungsten and copper. Tungsten boasts a high melting point, hardness, and resistance to arc erosion, while copper is renowned for its excellent electrical conductivity and thermal conductivity. This combination gives Copper-tungsten contacts high melting point, high density, hardness, good plasticity, low thermal expansion coefficient, excellent high-temperature resistance, strong corrosion resistance, good electrical and thermal conductivity, excellent arc resistance, and superior anti-welding properties.

Efficient heat dissipation: Under high-temperature conditions, the copper in Copper-tungsten contacts can liquefy and evaporate, absorbing a large amount of heat, effectively dissipating heat, and reducing the risk of performance degradation and damage caused by high temperatures.


Adjustable electrical conductivity and plasticity: By adjusting the copper content in the Copper-tungsten alloy, its electrical conductivity and plasticity can be optimized. A higher copper content typically means better electrical conductivity and plasticity, which are crucial for applications requiring good electrical contact and reliable mechanical properties.

Extensive application fields: Due to their superior performance, Copper-tungsten contacts are widely used in military, defense, aviation, navigation, electronic devices, medical equipment, and other fields. In these areas, Copper-tungsten contacts can meet the requirements for high reliability, stability, and long service life.

Application of powder metallurgy technology: Copper-tungsten alloys are typically produced using powder metallurgy techniques, which ensure the uniformity of alloy composition and stability of performance. By optimizing the powder metallurgy process, the performance and reliability of Copper-tungsten contacts can be further improved.

In summary, Copper-tungsten contacts, as a choice for high-performance electrical contact materials, exhibit unique physical and chemical properties, efficient heat dissipation, adjustable electrical conductivity and plasticity, and extensive application fields. These advantages make Copper-tungsten contacts an ideal choice for meeting the demands of high-performance electrical contacts.
