Tungsten needles can be used for microfabrication, which is the process of fabricating very small structures or devices on a microscale. Tungsten needles are often used in microfabrication for tasks such as etching or deposition of materials. They can also be used for fine-scale patterning of surfaces or for precision cutting or drilling of materials. The high melting point and hardness of tungsten make it well-suited for such applications, as it can withstand high temperatures and wear-resistant. Additionally, tungsten is a chemically stable material, making it compatible with many microfabrication processes that involve harsh chemicals or gases.
