Tungsten heavy alloys like WNiFe 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. Applications:  *  Protection shields for nuclear radiation  *  Balancing weights  *  Substitutional material for Uranium  *  Electroheat upsetting anvil block  *  Balls in bomb.  *  High voltage electrical contact  *  Electrodes for Resistance Welding Product Standard:   ASTM B 777 99
