Tungsten needles are slender and sharp metal needles made of tungsten metal. Due to the high melting point and hardness of tungsten, tungsten needles can be used in high temperature, high pressure, and high wear environments, and are often used in various industrial and laboratory applications.
The manufacturing process of tungsten needles generally includes selecting high-purity tungsten block materials, processing through multiple processes, including wire drawing, heating, cooling, polishing, etc., to make a slender and uniform tungsten needle. Its tip can be processed into various shapes, such as conical, spherical, flat, etc., to meet different application needs.
The main application areas of tungsten needles include the electronics industry, semiconductor industry, optical industry, aerospace industry, research laboratories, etc. For example, they can be used as key components in fields such as electron microscopes, atomic force microscopes, nanoprocessing, medical syringes, thermocouple probes, glass fusion, etc.
