Discharge tungsten pin is a special electrode material, usually made of tungsten, which has the advantages of high melting point, high hardness, high corrosion resistance and good electrical conductivity. It is mainly used in the fields of electric discharge machining, plasma cutting, arc welding and other fields. It can withstand high-frequency electric pulses and high currents, generate high-temperature and high-pressure arcs, and evaporate or dissolve metal materials on the surface of the workpiece to achieve precision machining. Discharge tungsten needles have a uniform organizational structure and good mechanical properties, and can meet the needs of various industrial fields.
Tungsten Electric Spark Discharge Needles: If tungsten discharge needles are mentioned in manufacturing or laboratory equipment, they may be referring to tungsten electrodes or tungsten probes used in electrical discharge machining. These electrodes are used to generate electrical sparks on metal or other conductive materials for cutting, engraving, or precision machining.
Tungsten Needles for Vacuum Equipment: In vacuum equipment, especially in applications such as scanning tunneling microscopy (STM), tungsten probes may be used. These probes are often very sharp to allow surface imaging and measurements at extremely small scales.
Medical Radiation Therapy Tungsten Needles: Another possibility is the radioactive tungsten needles used in radiation therapy. These tungsten needles may be used as radioactive sources to treat tumors.
