As an electrical contact material, tungsten copper alloy (WCu alloy) has excellent electrical conductivity, wear resistance, corrosion resistance, thermal expansion matching, high strength and pressure resistance, and high temperature stability. These properties make it an ideal material for electrical contacts and is widely used in many electrical devices.
Tungsten copper electrical contacts are suitable for a variety of electrical contact applications, including high current circuit breakers, contactors, relays, switchgear and transformers, etc. They can provide stable contact performance in high-load and high-frequency current transmission, reducing contact resistance and energy loss.
In the case of high-frequency arcing, the excellent electrical conductivity and wear resistance of tungsten copper electrical contacts enable it to maintain stable contact and transmit current in frequent switching environments. They are resistant to arc erosion and thermal shock, reducing the increase in contact resistance, thereby ensuring equipment reliability and performance.
WCu electrical contacts can also withstand current and thermal stress in high-temperature environments. Their high melting point and thermal stability allow them to maintain stable contact performance at high temperatures and prevent contact failure and disconnection caused by thermal expansion of the material. This makes them excellent in high temperature electrical equipment and high-power applications.
In addition, the electrical contacts also have good corrosion resistance and long service life characteristics. They are resistant to oxidation and attack by chemical media, reducing corrosion and wear of the contact surfaces, thereby prolonging the service life of electrical contacts.
As an electrical contact material, WCu alloy has many excellent characteristics. These characteristics make electrical contacts an ideal choice in the field of power transmission and control, providing critical support for the reliability, performance and life of electrical equipment.
