Tungsten needle is a kind of slender tungsten product made of pure tungsten or tungsten alloy. It has the advantages of high temperature resistance, high hardness and good conductivity. It can be used as electrode material in argon arc welding technology (the fastest developing and most widely used welding technology at home and abroad), as a probe of instrument, and as an anatomical needle.
China Tungsten online provides high quality tungsten needle products.
Tungsten needle
Among them, the appearance of argon arc welding tungsten needle electrode is round rod, which is usually suitable for welding thin plates below 4mm. The tungsten probe and dissecting needle are needle like. The tungsten probe is suitable for measuring the resistance of semiconductor materials in semiconductor material factories, semiconductor device factories, scientific research institutions and colleges and universities. Anatomic needle is suitable for all kinds of minimally invasive surgery.

Tungsten probe
Tungsten probe is a very fine and high purity tungsten probe with sharp tip, which is used in scanning tunneling microscope, micro structure gas detector and micro needle gas detector.
△ scanning tunneling microscope
Among them, scanning tunneling microscope (STM) is a new detection tool with atomic resolution, which has been widely used in physics, chemistry, biology, material science, microelectronics and other fields. Micro pattern gases detector (mpgd) is a kind of gas particle detector, which has been widely used in many fields such as X-ray, γ - ray, neutron imaging, astrophysics, solid state physics, biomedicine and nuclear medicine. LM is a new type of micro structure gas detector. In other words, STM probe, mpgd probe and LM probe are all made of high-purity tungsten wire.

Although the probes of the above microscopes can also be made of platinum wire, iridium wire, gold wire, silver wire and other metal materials with excellent conductivity, however, platinum wire, iridium wire and gold wire are expensive and can only be used when the requirements for tip surface interaction are high. The raw material for tungsten probe is high-purity tungsten wire with excellent conductivity, wear resistance, creep resistance, high hardness and high strength. Moreover, the preparation cost is relatively low, so it is naturally favored.
Tungsten needle for high frequency electric knife and pen
According to the principle of high-frequency electrotome, the high-frequency electrotome is a further improved electrosurgical product based on the high-frequency electrotome. It uses the high-frequency current generated by the electrotome to cut and coagulate human tissues.

Tungsten needle is a knife head consumable on the high-frequency electric knife pen. It has super sharp needle tip, which can realize precise cutting, low power and less smoke. It can solve the accident of poor hemostatic effect and burn caused by high-frequency electric knife operation power, high frequency and high voltage. It has high melting point and can withstand the high temperature above 3000 ℃, which is suitable for the whole machine Minimally invasive surgery of orthopedics, cardiothoracic surgery, pediatric surgery, orthopedics, etc.
Tungsten needle for internal ear anatomy
△ tungsten needle for anatomy
Tungsten needle has the advantages of high hardness, strong ductility and not easy to break, which is more suitable for inner ear anatomy than steel needle. In general, the tip of the steel needle is brittle and easy to fold, and the diameter of the tip can not be processed to micron level; while the tungsten wire has high strength, strong ductility, and is not easy to rust or break, durable. The coarse tungsten needle can be used to dissect the labyrinth of bone, and the superfine tungsten needle can be used to dissect the labyrinth tissue and cells of membrane.
