The mechanical properties of tungsten needles are affected by their diameter. In general, thinner tungsten needles have higher flexibility and lower strength than thicker needles. This is because thicker needles have more material, which makes them stiffer and stronger. However, thinner needles are often preferred for certain applications that require more flexibility, such as microinjection and microdissection. It is important to note that the mechanical properties of tungsten needles also depend on factors such as the specific alloy used and the manufacturing process.
