DESCRIPTION

Tungsten : Presentation

With a melting point higher than 3,410°C, tungsten has the best temperature behaviour of all common metals.

It is also noncombustible and offers very high mechanical characteristics.

The most common grades are alloys at >90%W + Ni/Fe or Ni/Cu.

Tungsten : Applications

Thanks to their extremely high densities, tungsten and tungsten alloys are suitable for X-ray and gamma ray shielding screens.

They are used in particular in the manufacture of collimator or container components.

Tungsten : Radiation protection properties

Tungsten has excellent resistance to gamma radiation.

However,under neutron flux, it produces capture gamma rays, with energies between 1 and 7 MeV and is strongly activated.
