What is copper tungsten alloy?

Copper-tungsten alloy, also known as tungsten copper, is a composite material combining copper and tungsten. The most common ingredient is a mixture of copper and tungsten, typically 10% to 50% tungsten by weight. The alloy is produced through a powder metallurgy process in which tungsten powder is mixed with copper powder and then sintered at high temperatures to form a solid composite material.

Copper-tungsten alloys are valued for their unique combination of properties, including copper’s high thermal and electrical conductivity and tungsten’s high strength, hardness and wear resistance. These properties make copper-tungsten alloys suitable for a range of applications including electrical contacts, resistance welding electrodes, EDM (electrical discharge machining) electrodes and other high temperature and high wear applications where electrical and thermal conductivity are combined with high strength and resistance is required.

Embedding tungsten in copper creates a composite material that combines the beneficial properties of both metals. Tungsten has high strength, hardness and wear resistance, while copper has high thermal and electrical conductivity. By embedding tungsten into copper, the resulting alloy exhibits a unique combination of properties, making it suitable for a variety of applications requiring high strength and good electrical conductivity. For example, in the case of tungsten-copper electrodes, tungsten provides the hardness and wear resistance needed to process hard materials, while copper ensures efficient heat dissipation and electrical conductivity. Likewise, in the case of copper-tungsten alloys, the combination of tungsten and copper provides a material with excellent thermal and electrical conductivity as well as high strength and wear resistance.

Copper is a better conductor of electricity than tungsten. Copper is known for its excellent electrical conductivity, which makes it the material of choice for wires, electrical contacts, and various electrical applications. On the other hand, tungsten has a lower electrical conductivity compared to copper. While tungsten is valued for its high melting point, strength, and hardness, it is not as efficient an electrical conductor as copper. Therefore, for applications where high electrical conductivity is the main requirement, copper is the first choice over tungsten.
