Tungsten alloys are materials with a high tungsten content and low amounts of Ni Fe or Ni Cu.

Advantages:
  *  High density (17.0~18.5g/cm3)
  *  Good machinability
  *  Good mechanical properties
  *  High modulus of elasticity
  *  High absorption capacity against χ-rays and γ-rays
  *  Harmless to the health and environment.
