Tungsten Copper Contacts

Comprising a blend of tungsten and copper, tungsten copper contacts embody the favorable characteristics of both metals, including heat resistance, aberration resistance, high density, and outstanding thermal and electrical conductivity. Ideally suited for electrical discharge machining (EDM), these contacts demonstrate remarkable wear resistance, a proficient metal removal rate, and the ability to maintain intricate detail.

Copper Tungsten Contact Parts

Under intense arcing conditions, copper tungsten contact parts exhibit a consistently regular shape, experiencing only a uniform roughening effect without the occurrence of cracks or burn-off droplets. Copper tungsten contact parts are utilized in various applications, including SF-6 circuit breakers, load break switches, transformer step switches, resistance welding electrodes, and spark erosion electrodes.

Copper Tungsten Contact Tips

Even in challenging arcing conditions, copper tungsten contact tips consistently retain their regular shape, exhibiting only a uniform roughening effect without the formation of cracks or burn-off droplets. Copper tungsten contact tips are employed in various applications, including SF-6 circuit breakers, load break switches, transformer step switches, resistance welding electrodes, and spark erosion electrodes.

Tungsten Copper Arc Contact

Tungsten copper arc contacts are applied as arcing elements in SF6 circuit breakers designed for ultra-high, high, and medium voltage applications. Positioned at the core of the switching chamber, these tungsten copper contacts endure rigorous mechanical and thermal stresses. During the opening and closing of the circuit, the arc initiates directly at the switch contacts, reaching temperatures of up to 20,000°C.

Tungsten Copper Contacts Spares

Tungsten copper contact spares undergo intense mechanical and thermal strains during operation. Temperatures surge to several thousand degrees for brief moments due to arcing. Only materials composed of tungsten copper can withstand these elevated temperatures and resist aberrations.

Tungsten Copper Electrical Contacts

Tungsten copper electrical contacts are the optimal material for electrical discharge machining (EDM) applications, offering outstanding wear resistance, a commendable metal removal rate, and the capacity to preserve intricate details. They are employed in scenarios where speed and wear resistance take precedence.

Tungsten Copper Spring Contacts

Tungsten copper spring contacts exhibit exceptional resistance to arc burning and welding, superior arc-breaking performance, good thermal conductivity, minimal thermal expansion, high-temperature stability without softening, elevated strength, high density, and remarkable hardness, among other distinctive characteristics.

Tungsten Copper Fiber Structured Contact

Tungsten copper contact materials with a fiber structure surpass their power metallurgical counterparts, and the ablation resistance of small-diameter fiber-structured contacts excels compared to larger ones. These materials boast not only a high melting point, high density, and low thermal coefficient of expansion, but also exhibit superior electric conduction, heat conduction, and plasticity at room temperature.

Tungsten Copper Arcing Contacts for SF6 Circuit Breakers

Tungsten copper materials find application as arcing contacts in high and medium-voltage SF6 circuit breakers. Positioned at the core of the switching chamber, these tungsten copper arcing contacts endure intense mechanical and thermal stresses. Temperatures during arcing can surpass 20,000 K, for example.

Tungsten Copper Vacuum Contacts

Tungsten copper contacts play a crucial role in the vacuum arc-quenching chambers (VACs) of reliable, fast-acting vacuum circuit breakers designed to interrupt substantial currents in high-voltage 6-35 kW electrical networks. The tungsten copper vacuum contact serves as a vital component in commutation switches (circuit breakers). Presently, the prevailing material for contact pairs in VACs is comprised of W-(50-90%) Cu composites.

Tungsten Copper High Voltage Arc Contacts

T&D provides an extensive selection of high-voltage arc tungsten copper contacts. Depending on the desired balance of electric arc resistance and electrical conductivity, our customers can easily identify the ideal contact material that enhances the performance of their electrical equipment.

Tungsten Copper Combination Contact

A combination contact is a fusion of tungsten copper with another material. Typically, the contact’s shank is made of iron, while the end consists of tungsten copper. In comparison to standard tungsten copper contacts, the combination contact offers a cost-effective solution. This makes it particularly suitable for industries that demand high quality at the contact end, allowing significant cost savings without compromising on performance.
