Tungsten has the characteristics of high melting point, high strength and hardness, good performance at high temperature, low resistivity, small expansion coefficient, and small electronic work function; therefore it is the metal material which is most widely used in high-temperature conditions. Our company produces a variety of tubes, rods, plates, ingots, crucibles and various large-scale special-shaped products made of pure tungsten, such as parts of high temperature furnace, components of electronic tubes, semiconductors and high temperature crucibles, anodes for lamps, various electrodes, glass industry parts, thermocouple bushing, porous body and complex, etc.
