Tungsten needles are known for their high durability and resistance to wear and deformation. Tungsten is a very hard and dense metal, which makes it highly resistant to abrasion and other forms of mechanical wear. Additionally, tungsten has a high melting point and can maintain its mechanical properties at high temperatures, making it suitable for use in applications that involve high temperatures or exposure to extreme conditions.
The durability of tungsten needles can also be enhanced by various surface treatments and coatings, which can further improve their resistance to wear and corrosion. For example, tungsten needles can be coated with materials such as diamond-like carbon (DLC), which can increase their hardness and reduce friction, resulting in longer-lasting and more reliable performance.
Overall, the durability of tungsten needles is a key advantage of this material, particularly for applications that involve high stress, wear, or temperature. Tungsten needles can withstand repeated use and remain sharp and functional for longer periods of time than many other types of needles, making them a popular choice for a wide range of scientific and industrial applications.
