A tungsten needle is a very thin, pointed metal instrument made primarily of tungsten. Tungsten is a rare and hard metal with a high melting point and excellent electrical conductivity, making it useful for various industrial and scientific applications.
Tungsten needles are commonly used in scientific research, especially in electron microscopy, where they are used to manipulate or probe specimens under high magnification. They are also used in industrial settings for tasks such as cutting and welding, as well as in medical settings for procedures such as acupuncture.
Tungsten needles come in various shapes and sizes depending on their intended use, but they are typically very thin and pointed, with a diameter ranging from a few microns to a few millimeters. They are usually made by drawing tungsten wire through a series of progressively smaller dies, resulting in a highly refined and precise instrument.
