Refractory Metals
Radiation Shielding Parts
Tungsten heavy alloy is the right material for radiation shielding applications such as in medical, security and inspection equipment , as its combination of higher density (more than 60% denser than lead), good machinability, corrosion resistance, excellent radiation absorption (superior to lead and steel), simplified life cycle and high strength.
Tungsten heavy alloy VS Lead
● Higher density
● Better radiation absorption
● Volume saving
● Non-toxic, environment friendly
● Longer service life
● No license required
