Tungsten needle is an elongated tungsten product made of pure tungsten or tungsten alloy, having the advantages of high temperature resistance, high hardness, and good conductivity. Tungsten needle can be used as an electrode material for argon arc welding (the fastest growing and most widely used welding technology at home and abroad), as a probe needle for detecting instrument, or as a dissection needle for various minimally invasive surgery.

Wherein, tungsten needle electrode for argon arc welding applications has a round rod shape, which is generally suitable for welding thin plates of thickness of 4 mm or less. While probe tungsten needle and dissection needle are pointed needles. Probe tungsten needle is suitable for semiconductor material factory, semiconductor device factory, scientific research unit, colleges and universities to test the resistance performance of semiconductor materials. And dissection needle is suitable for minimally invasive surgery such as cosmetic surgery.
