What is Application scenarios and advantages of tungsten needles?
Advantages
Tungsten needles are highly regarded due to their unique properties, demonstrating significant advantages across various application domains. Here are some of the advantages:
Wear Resistance: Tungsten needles, made from 99.95% tungsten , exhibit exceptional hardness and wear resistance. This makes them well-suited for environments characterized by friction and abrasion, such as high-speed machining and precision engineering, where prolonged and intensive use is required.
Precision Dimension: the diamter of the Tungsten needles can be min0.2mm, we can offer Pointed Tungsten Needle, Tungsten Probe, Tungsten discharge Needles , We have almost all the sizes in stock and can provide you with immediate delivery, In the aspect of intensive processing of needles treating, bending forming, slotting, open pore and thread with advanced technology and experiences.can be precisely machined to meet specific requirements,the most of size can boasting high dimensional accuracy. They are particularly valuable in micro-scale machining, where high-precision tools like tungsten needles are essential for the fabrication and assembly of tiny components.
High-Temperature Resistance: With outstanding heat resistance, tungsten needles maintain stability even under extreme temperatures. This widespread attribute allows tungsten needles to play crucial roles in industries such as aerospace, automotive manufacturing, and electronics, where high-temperature processing and welding are commonplace.
Corrosion Resistance: Tungsten needles possess excellent corrosion resistance, able to withstand the corrosive effects of acids, alkalis, and other chemicals. This quality makes them highly desirable in fields like chemical engineering, biomedicine, and more, where resistance to corrosion is paramount.
Electrical Conductivity: While not as high as some other metals, tungsten still exhibits good electrical conductivity, making tungsten needles useful in electrical discharge machining (EDM), electrical contacts, and other electrical applications.
Longevity: Due to their exceptional wear and corrosion resistance, tungsten needles boast a long service life, capable of enduring prolonged and repetitive usage without degradation. This longevity not only reduces production costs but also enhances operational efficiency.
Application
