Channel：Tungsten 标签： Tungsten  electrode 

简介：Tungsten electrode has a high melting point, high temperature strength and creep resistance and thermal conductivity, electrical conductivity and electron emission characteristics are good, heavy. Low coefficient of expansion and the lowest vapor pressure of the metal. The general approach to the preparation of powder metallurgy. Tungsten electrode is widely used in welding, high voltage anode, cathode discharge and thermal conduction devices.
Our tungsten electrode materials with high purity tungsten powder through advanced technology and strict control of multi-channel process to ensure purity. All the electrodes are made of pure tungsten and melt
