Tungsten pin is a kind of tungsten product made of pure tungsten or tungsten alloy electrode material, which is ground into a tip by one end.
Grinding range: tungsten electrode diameter 0.5mm-6.0mm
Grinding tip angle: 0-70°
Purity: W≥99.95%
Melting point: 3420 °C / 3693 K
Common diameters of tungsten needles: 0.1mm, 0.5mm, 0.7mm, 1.0mm, 1.6mm, 2.0mm up to 12mm.
The main uses of tungsten needles are as follows:
1. Cathode discharge needle
Tungsten needle can be used for ion fan, ion drum, ion gun, ion snake, electrostatic bar and other equipment as a cathode to emit electrons.
Ion fan tungsten needle common specifications: 1.0 * 15mm, 1.0 * 30mm, 1.0 * 10mm, 1.5 * 0.8mm, 1.5 * 10mm, 1.5 * 15mm, 1.5 * 20mm
2. For electronic probe components
For digital four-probe tester, four-probe resistivity square resistance probe, silicon material compound tester, semiconductor conductive model identifier, etc.
3.Tungsten level argon arc welding
In the welding process using AC or DC, we can use ground tip pure tungsten, cerium tungsten, thorium tungsten electrode. In the case of low current or welding thin materials, the sharpened tungsten pin works better than ordinary electrodes because it directs the current into a concentrated arc and helps prevent them from twisting. However, higher current applications are not recommended because the tip of the pointed tungsten electrode falls off and can lead to contamination.
