Tungsten carbide needles have good electrical conductivity. Its resistivity is 5.5×10^-8Ω m, which is one of the highest among many metals. It is about 5 times higher than that of copper and higher than that of iron. About 20 times. Tungsten carbide needles are widely used in electronic components, semiconductor devices and other fields due to their excellent electrical conductivity, high strength, and high hardness.
