The types of tungsten electric needles are mainly divided into the following types:
1. Whisker-type tungsten needle: a tungsten material with a whisker structure formed by high-temperature heat treatment of pure tungsten or tungsten alloy powder. This tungsten needle has high strength, wear resistance, and corrosion resistance, and is usually used in oil drills, high-temperature vacuum furnaces, test equipment under extreme conditions and other fields.
2. Tungsten needle electrode: mainly used for high-temperature, corrosion-resistant, and high-strength electrodes in the fields of argon arc welding, plasma arc welding, electric cutting, electrochemical processing, vacuum arc, etc. Common manufacturing methods include pure tungsten electrodes, tungsten-molybdenum electrodes, tungsten steel electrodes, etc. Different types of tungsten needles can be selected according to different uses.
3. Tungsten needle with a pointed tip: mainly used for instrument probes, such as digital four-probe testers. This equipment is a multi-purpose comprehensive measurement equipment that uses the four-probe measurement principle. It is suitable for semiconductor material factories, semiconductor device factories, scientific research institutions, and colleges and universities to test the resistance performance of semiconductor materials.
The types of tungsten electric needles mainly include whisker-type tungsten needles, tungsten needle electrodes, and tungsten needles with a pointed tip. Different types of tungsten electroacupunctures have different characteristics and application fields, and need to be selected and used according to specific needs.
