Tungsten Electrode (W Electrode) Description:
Tungsten’s high melting point makes it an ideal material for electrodes. Pure tungsten electrodes and other tungsten electrodes are all available through SAM. Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding (GTAW) electrodes.
