Tungsten needles are known for their excellent wear resistance due to their high melting point, high hardness, and low coefficient of friction. In microscale applications where repeated use is necessary, tungsten needles can be a good choice due to their ability to maintain their shape and sharpness over time. Compared to other materials commonly used in microscale applications such as stainless steel, tungsten needles are generally more wear-resistant. However, the wear resistance of tungsten needles may be affected by the specific application and the conditions in which they are used.
