Tungsten Needle Electrode
Tungsten Needle Electrode Description & Application
Tungsten needle is a kind of super-tipped electrode commonly used in various industrial instruments. Generally, it can be divided into two types: pointed tungsten needle and round rod tungsten needle. One or both ends of the tungsten needle electrode is made of pure tungsten or tungsten alloy, and its surface can be polished and matte as required. Tungsten needle electrodes have superior wear resistance, heat resistance and durability. Therefore, it can be widely used in metal welding and engraving, electronic probe device, precision instrument probe, glass processing and single particle processing and other fields. It should be noted that the tungsten needle electrode is often used in combination with the needle holder, and its tip is easy to bend or break, so we should pay attention to equipping a special storage box during storage and use, and it is rarely used for processing hard materials, and tungsten needles can be continuously increased. service life.
