Product Description

Tungsten Copper Contacts are electrical contact materials synthesized using powder metallurgy, with tungsten (W) and copper (Cu) as the main components. Combining the high temperature resistance and hardness of tungsten with the high conductivity of copper, Tungsten-Copper Contact Tips are indispensable core components in electrical equipment, widely used in high-voltage and high-temperature environments in power systems, industrial equipment, automobiles, aerospace, and other specialized fields. With continuous advancements in modern technology, the performance of Tungsten-Copper Contact Points has been continuously optimized, making them a crucial component in high-voltage electrical appliances, electrical switches, and precision electronic equipment.

Product Advantages

High Temperature Resistance and Arc Resistance

Tungsten's high melting point (3410℃) and excellent arc resistance enable Tungsten-Copper Contact Points to operate stably under extremely high-temperature conditions. When a large current passes through the contacts, a strong arc discharge occurs. Tungsten, with its extremely high melting point and excellent resistance to arc erosion, effectively prevents damage to the contacts caused by arc burning, significantly extending the equipment's service life. This is particularly evident in high-voltage power equipment and circuit breakers, where frequent interruption of large currents is required, ensuring reliable operation even under harsh conditions.

Low Contact Resistance and High Conductivity

Copper possesses excellent conductivity, approaching that of silver and ranking among the highest of all metals. This ensures stable and efficient current transmission between contacts. Tungsten-Copper Contact Elements fully utilize this advantage of copper in their design. Through a reasonable material ratio and structural design, contact resistance is effectively reduced, current conduction efficiency is improved, and Joule heating caused by resistance during operation is minimized, preventing performance degradation due to localized overheating.

Excellent Mechanical Strength and Wear Resistance

Tungsten-Copper Contact Pieces combine the high hardness of tungsten with the machinability of copper, resulting in excellent mechanical strength and wear resistance. Tungsten's high hardness makes the contact surface less prone to wear, while the addition of copper enhances the material's toughness and machinability, facilitating the manufacture of contact structures with various complex shapes. This allows the contacts to maintain stable connection performance during prolonged contact and insertion/removal, reducing contact defects or failure rates caused by wear, and ensuring the stability and reliability of equipment during long-term operation.
