the Extensive Applications of Tungsten Needles in Industry

Tungsten needles, composed of refractory alloys, are ultra-sharp electrodes widely used across various industrial sectors. Their advantages, such as excellent conductivity and high-temperature resistance, make them an indispensable functional material in modern industry.  Electrical Discharge Machining (EDM) and CNC Machining Tungsten needles are extensively used in electrical discharge machining (EDM) and computer numerical control (CNC) machining. They can precisely process various metal materials such as carbon steel, stainless steel, silicon copper, copper, bronze, and titanium. The high hardness and wear resistance of tungsten needles enable them to withstand high temperatures and pressures, ensuring machining accuracy and efficiency.  Welding Applications Tungsten needles play a significant role in the welding field, especially in tungsten inert gas (TIG) welding. During welding, an arc is created between the tungsten electrode and the workpiece, and filler metal is fed into the weld pool formed by the heat of the arc. Due to their high melting point and temperature resistance, tungsten electrodes prevent melting and burn-off, making them ideal for welding thin sheets (up to 4mm) such as pipes and tube-to-tube plate connections.  Instrument Probes Sharp-tipped tungsten needles are primarily used as instrument probes. For example, in digital four-probe testers, which measure the resistivity and sheet resistance (thin layer resistance) of semiconductor materials. The fine tips of tungsten needles ensure precise contact with the material being tested, obtaining accurate measurement data and improving the precision and reliability of testing.  Discharge Machining Tungsten needles are also used in discharge machining processes. During discharge machining, both the workpiece and the electrode (tungsten needle) are immersed in a dielectric fluid, and high-voltage pulses create sparks between the workpiece and electrode, causing localized melting and evaporation of the workpiece surface to achieve machining. The high melting point and temperature resistance of tungsten needles ensure their stability and durability in discharge machining.  Air Purification In air purification systems, tungsten needles serve as discharge electrodes. By applying high voltage to the tungsten needle, corona discharge is generated, which charges airborne particles, allowing them to be collected and thus purifying the air. The high-temperature resistance and corrosion resistance of tungsten needles ensure their stability and longevity during the discharge process.  Military Applications Tungsten needles have significant applications in the military field. Historically, tungsten was used in weaponry during the cold weapon era. For instance, Chinese archaeologists have detected tungsten in excavated "treasured swords." During World War I, German arms engineers highly valued tungsten-containing gun barrels. Data from that time showed that Russian and French light machine guns could fire around 6,000 rounds before wearing out, whereas German light machine guns, utilizing tungsten, could fire up to 15,000 rounds, more than doubling the performance. The high hardness and wear resistance of tungsten make it widely used in military equipment.  In conclusion, tungsten needles, with their exceptional physical and chemical properties, have extensive applications across various industrial fields. They are an indispensable functional material in modern industry. With technological advancements, the applications of tungsten needles in industry are expected to become even more widespread and profound.
