Cerium tungsten pin is tungsten pin products added rare earth cerium oxide in tungsten base through powder metallurgy and rolling polishing process produced. Non radioactive material.
Cerium tungsten is the electrode in pure tungsten ingredients containing 1.8%-2.2% of cerium oxide and impurity is less than or equal to 0.1%. The utility model has the advantages of X ray dose and antioxidant properties of cerium tungsten than thoriated tungsten is greatly improved; electronic work function of about 10% lower than the thorium tungsten electrode, the arc more easily, arc stability is better. In addition cerium tungsten good chemical stability, cathode spots such as small, lower pressure drop, less loss, so it is a tungsten is currently the most widely used in TIG welding.
