Tungsten Copper Electrical Contacts Are Suitable for a Variety of Electrical Contact Applications

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.

Why Tungsten-copper Alloys Can Be Used as Electrical Contacts?

Tungsten-copper alloys are widely used as electrical contacts. An electrical contact is a key component used in the transmission and control of power and is commonly found in electrical equipment such as switchgear, relays, circuit breakers and contactors. 

The following is an overview of tungsten copper alloy as an electrical contact material:

Excellent electrical conductivity: Tungsten-copper has good electrical conductivity, which is an ideal combination of the electrical conductivity of copper and the high melting point of tungsten. Compared with pure copper material, it has lower resistance and higher conductivity, which can provide better current transmission and conductivity efficiency.

High wear resistance and corrosion resistance: Tungsten-copper has excellent wear resistance and can maintain stable contact performance in high frequency arc, high current and high temperature environments. In addition, it has excellent corrosion resistance, which resists oxidation and chemical attack, thereby prolonging the service life of electrical contacts.

Stable size and thermal expansion matching: The alloy has good dimensional stability when the temperature changes, and can maintain contact force and connection stability. In addition, its thermal expansion coefficient is close to that of other commonly used materials such as steel and aluminum, which is beneficial to reduce contact failure caused by thermal expansion and contraction.

High strength and pressure resistance: The alloy has high strength and hardness, can withstand large pressure and load, and is not easy to deform and damage. This allows it to maintain good mechanical stability under high current and high load conditions, thereby improving the reliability and life of electrical contacts.

High temperature stability: The alloy has high melting point and good thermal stability, and can maintain stable performance in high temperature environment. It can withstand arc, current and thermal shock at high temperature, reducing the increase of contact resistance and thermal fatigue of materials.

Tungsten Copper Alloy: A Versatile Material for Demanding Applications

Tungsten copper alloy combines the advantages of copper and tungsten, with the advantages of high strength, high specific gravity, high temperature resistance, arc ablation resistance, good electrical and thermal conductivity and good processing performance.

Given that, it has various applications as following:  

Electrical Contact Material

Owing to high temperature resistance and electric ablation resistance, in the 1960s, some advanced countries used tungsten-copper alloys to manufacture electromagnetic fuses, throat linings on rockets and missiles, and other components. In addition, in the field of electrical contact, the performance of the contact material basically determines the development trend of the high-voltage switch. Tungsten-copper alloy material has high conductivity, electric ablation resistance and good breaking performance, and is widely used as contact material for high-voltage and ultra-high-voltage switching appliances.

Heat Sink Material

As a heat sink material, the material has high requirements for the uniformity of the structure, air leakage rate, thermal conductivity, and thermal expansion coefficient. Therefore, according to actual needs, tungsten-copper alloy materials can be adjusted by using tungsten and copper elements to change the thermal expansion coefficient and thermal conductivity, which can effectively avoid fatigue damage caused by thermal stress and affect the performance of tungsten-copper alloy materials. At the same time, the alloy material is widely used in inserts, connectors and heat dissipation components because tungsten and copper are composite materials, and have gradually become important heat sink materials.

Electrode Material

Electrode material is a key material in EDM, and it is directly related to stability, precision, and surface roughness of joints. Due to the relatively poor ablative properties of general electrode materials and high motor consumption, the processing accuracy is relatively poor, and even multiple processing is required. For this reason, with the development of tungsten-copper alloy materials, in order to solve the disadvantages of EDM, the WCu alloy material can be used to make electrical machining electrode materials, which can not only effectively improve the accuracy and reliability of machining, reduce electrode consumption.
