Tungsten is known for its high thermal conductivity, which makes it an excellent choice for microscale heat transfer applications. In fact, tungsten has one of the highest thermal conductivities of all pure metals, with a value of about 174 W/mK at room temperature. This is comparable to other materials commonly used in microscale heat transfer applications, such as copper (about 400 W/mK at room temperature) and aluminum (about 237 W/mK at room temperature).
The high thermal conductivity of tungsten allows it to rapidly conduct heat away from a heat source, making it useful in applications such as microscale heat sinks and thermal management systems. Additionally, tungsten has a relatively high melting point (about 3422 °C), which allows it to withstand high temperatures without melting or degrading. This property makes it useful in high-temperature applications such as microscale furnaces and heaters.
