Tungsten is known for its exceptional high-temperature strength and stability. It has a very high melting point of around 3,422°C (6,192°F), which is the highest melting point of any metal. This makes tungsten needles capable of withstanding extreme temperatures without melting or deforming, making them useful in high-temperature applications.
Tungsten needles can also maintain their strength and hardness at high temperatures. They have a low coefficient of thermal expansion, which means they do not expand significantly when heated. This makes them useful for applications that require dimensional stability at high temperatures.
Tungsten needles are commonly used in high-temperature applications, such as in furnace and thermal analysis, where they can withstand temperatures of up to 3,000°C (5,432°F). However, tungsten needles can become brittle at low temperatures, so they may not be suitable for applications that require low-temperature performance.
