W1 99.95% Pure Tungsten Rod Ground Tungsten Rods / Electrode For Vacuum Furnace
Tungsten has the highest melting point of all metals and is therefore also suitable for very high-temperature applications. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability.
