Tungsten is a refractory metal with the highest melting point. Generally higher than the melting point 1650 ℃ and a storage amount of metal zirconium and melting point higher than the melting point (1852 ℃) of metal is called refractory metal. As a kind of refractory metal, tungsten is the most important advantage is good high temperature strength, good corrosion resistant to molten alkali metals and steam performance.
