Tungsten has a high melting point and can withstand high temperatures. Therefore, tungsten needles can operate in a wide temperature range, from -270°C to over 3,000°C, depending on the specific application. The optimal temperature range for tungsten needles to operate in depends on the specific application and the composition of the tungsten needle. In general, tungsten needles are commonly used in high-temperature applications where other materials would fail, such as in furnace heating elements and thermocouples.
