Tungsten, an element with symbol W and atomic number 74, has the highest melting point of all known metal. It is characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability.
Many practical applications of tungsten are based on its high melting point and density and its low vapor pressure. Tungsten is an excellent material for high vacuum technology, dimensional stability, glass seals and furnace construction. It is also alloyed with other materials such as nickel, copper and iron to provide high-density machinable materials.
