In high-frequency applications, some common wire materials are suitable for providing better performance, including:

Pure Copper Wire: Pure copper wire has good electrical conductivity and low resistance, making it a common choice for high frequency applications. It has lower resistive loss and smaller skin effect, and is suitable for higher frequency circuits and communication systems.

Copper-clad silver conductor: Copper-clad silver conductor has the advantages of high conductivity of silver and good processability and corrosion resistance of copper. They provide lower resistive losses and more uniform current distribution in high frequency applications.

Pure Silver Wire: Pure silver is one of the best conductive materials and has very low resistance and skin effect. In high-frequency applications, pure silver wire provides the best electrical performance, but it is more expensive and is usually used in high-end applications with specific requirements.

Alloy wire: Certain alloy materials, such as copper-tin alloy, copper-nickel alloy, etc., also have good performance in high-frequency applications. These alloys can improve the resistance and skin effect of wires and provide better corrosion resistance.

Isotropic Wire: Isotropic wire is a specially designed wire designed to reduce skin effect and resistance. They usually use a multi-stranded structure to allow the current to be distributed more evenly across the conductor cross-section.

When selecting conductor materials for high-frequency applications, factors such as frequency range, resistance requirements, cost, and corrosion resistance need to be considered, and the selection should be based on the needs of the specific application. It is also important to consult professional engineers or refer to relevant standards and specifications.
