The price of different types of tungsten electrodes varies greatly, mainly affected by factors such as the type, content, manufacturing process and market supply and demand of doped elements. The price of pure tungsten electrodes is relatively low because of their single material and relatively simple production process, making them suitable for applications such as AC welding aluminum-magnesium alloys. The price of thorium tungsten electrodes is medium to high, although the content of thorium element is not large, but because of its radioactive particularity, the handling and transportation requirements are stricter, and the cost is higher.
The price of non-radioactive rare earth tungsten electrodes such as cerium tungsten and lanthanum tungsten is usually higher than that of pure tungsten and thorium tungsten because of their more complex doping process, excellent performance and longer service life, suitable for high-end welding needs. The price of zirconium tungsten electrode is similar to that of lanthanum tungsten, and it is mainly used for AC welding aluminum alloys. Rare earth multi-element tungsten electrodes have the best performance due to their doping of a variety of rare earth oxides, and are usually the most expensive.
