Drawings:

Technical request:
1, The center line of the grooves and that of the module must be
coincident, and the tolerance should not be greater than 0.01mm.
2,The dimensional tolerance of the center distance of the alignment
seam must be guaranteed.
3,The alignment joint and the installation base surface must be
vertical, and the verticality is ensured to be 0.01.
4, The material density should not be less than 18.3g/cm3. The
shielding part should be cleaned after processing.

Application:
Radiation protection and guidance:
Because of its high density (~18.8 g / cm3), and excellent X-ray,
gamma ray absorptive capacity, excellent process ability, making
Tungsten Nickel Iron alloy become ideal material for radiation
therapy collimator and protection components.
Balance weights:
It is widely used in automobile crankshaft counterweight, oil
weight, security defense, precision optical instruments, due to the
magnetic properties, high proportion of tungsten copper nickel
alloy especially for in the aviation electron system.
Special application, it has the following two characteristics:
1, material particularity, tungsten, nickel and iron, the main role
of shielding radioactive radiation, generally used in medical
devices.
2, the particularity of its own structure, which is relatively
heavy. The tight joint between the internal and external threads
can completely shield the overflow of radiation.
