Manufactured under the glow discharge condition by carbonyl tungsten vapor, tungsten needle is an elongated-structure product made of pure tungsten or tungsten alloy. Tungsten needle processes many advantages like high temperature resistance and good electrical conductivity. Under 1500 ° K indoor substrate temperature, the length of tungsten needle will grow but, when the temperature is above or below 1100 ° K, the form and crystalline state of the needle top will change. At low temperature, the shape of agglomerated tungsten particles looks like branches while at higher temperature it resembles beard.

Tungsten needles can be used as apparatus probes or electrode materials in argon-arc welding technology. They are widely applied in the surface of carving metal and cutting process of collodion particles. Since the pin is very fragile, it is easily to be bent or broken and manual operation is advised in the process.

Classified by the shape difference, tungsten needle can be divided into round rod and pointed needle. According to the production process, there are two ways to manufacture, namely metal injection molding process and wire-drawing molding process.
