Tungsten
    Publish time 2019-07-27 12:27    

Atomic Symbol:    W

Atomic number:    74

Melting point:     3410 DC

Density:         19.3 g/cm3


Tungsten is one of our main product. It has the highest melting point (3410°C) of the four common refractory metals. with a density of 19.3 gm/ cc, it is only surpassed by rhenium and osmium in weight. Tungsten has a long history of use for filaments in the lamp industry.Tungsten has the best high-temperature strength of all the refractory metals. For this reason, it is used in very high temperature vacuum furnaces,
