Tungsten rods, tungsten rods, tungsten rods and tungsten electrodes are finished products of pure tungsten metal processed by high temperature and high pressure. The appearance is black or bright silver depending on the processing technology. Tungsten rods have the characteristics of high melting point, low thermal expansion coefficient and good thermal conductivity, and are widely used in traditional industry and military.
Mainly used for drawing tungsten wire, processing ion implantation parts, manufacturing electric light source and electric vacuum parts, used as high-temperature heating element and high-temperature structural parts, used as electrodes in the rare earth industry, and machined into pure tungsten electrodes.
