Resistivity of Tungsten

Tungsten, also known as wolfram, is a key material in electrical engineering. It is highly valued for its resistance to heat and electricity, which makes it an ideal material for use in electrical applications. But what exactly is the resistivity of tungsten?

What is Resistivity?

Before we can discuss the resistivity of tungsten, it’s essential to understand what resistivity actually is. Resistivity is a measure of how well a material resists the flow of electricity. It’s measured in units called ohms and is calculated by dividing the voltage applied to a sample by the current flowing through it. The higher the resistivity of a material, the better it will be at resisting electric currents.

Tungsten Resistivity

Tungsten has one of the highest resistivities of any metal, making it an ideal choice for electrical applications that require high levels of resistance. Its resistivity ranges from 5 x 10-8 Ωm to 5 x 10-7 Ωm depending on its exact composition and temperature. This range places tungsten among some of the most resistant materials available and makes it invaluable for creating circuits that require high amounts of resistance without losing too much efficiency or power output.


In conclusion, tungsten is one of the most popular materials used in electrical engineering due to its high level of resistance to electricity and heat. Its resistivity ranges from 5 x 10-8 Ωm to 5 x 10-7 Ωm depending on temperature and composition, making it an excellent choice for circuits that require large amounts of resistance without sacrificing efficiency or power output. If you’re looking for a reliable material for your next electrical project, consider using tungsten!
