What Are Electrical Properties of Cemented Carbide?

Cemented carbide is an alloy material made from a hard compound of refractory metal and a bonding metal through a powder metallurgy process. Due to its unique structure and chemical composition, cemented carbide has some electrical properties.

The electrical conductivity of cemented carbide varies depending on composition and process. Generally speaking, tungsten carbide-based cemented carbide has low electrical conductivity, high resistivity, and certain insulation properties. In addition, cemented carbide also has low dielectric constant and dielectric loss factor, which makes it have certain application value in some high-frequency and microwave engineering.

It should be noted that the electrical properties of cemented carbide are not its dominant properties, so the electrical properties need to be evaluated and optimized in some specific application scenarios. At the same time, the stability of the electrical properties of cemented carbide in high temperature environments is also an issue that requires attention.
