Product Details

arc welding, furnace melting. Besides pure tungsten electrode, we also produce other tungsten alloy electrode, such as yttrium tungsten electrode, cerium tungsten electrode, lanthanum tungsten electrode, thorium tungsten electrode and zirconium tungsten electrode, and they all have their specific application.

Properties of tungsten electrode:
Tungsten electrode features high melting point, strong electron emission capacity, high elastic modulus and low vapor pressure. In addition, for the specific tungsten alloy electrode, take thorium tungsten electrode as an example, it has the advantages of high crystallization temperature, good electronic conductivity and better property of mechanical cutting.
