7. The Cerlum-tungsten electrode is a tungsten electrode product which is prepared by adding powdered metallurgy and calendering and polishing process to the tungsten base. It is the earliest non-radioactive tungsten electrode product produced in China. The product is characterized by low current conditions. Excellent arcing performance, small arc current. Therefore, it is often used for the welding of pipes, stainless steel products and small precision parts. Under low current DC conditions or electrode diameters below 2.0 mm, Cerlum tungsten electrodes are the preferred alternative to tantalum tungsten electrodes.

Production process
Tungsten, with a melting point of up to 3420ºC, has excellent high-temperature strength and good corrosion resistance to molten alkali metals and vapors. Its own high thermal stability ensures that it can still work normally in high temperature environment.
Tungsten has the advantages of high melting point, high strength and hardness, high temperature performance, low resistivity, small expansion coefficient, small electronic power and so on. It is a widely used high temperature resistant metal material.
