Tungsten Heavy Alloy

 Tungsten Heavy Alloys are materials with a high tungsten content and low amounts of Ni,  Fe or Ni, Cu. Some tungsten alloy is added Co, Mo or Cr etc. Their densities could be as  high as 16.8~18.8g/cc.

1.Advantages:

                   * High density

                   *  Good machinability

                   *  Good mechanical properties

                   *  High modulus of elasticity

                   *  High absorption capacity against χ-rays and γ-rays

                   *  Harmless to the health and environment.

2.Applications:

                   *   Protection shields for nuclear radiation such as PET syringe shield, vial shiel  isotope container, FDG container, multi leaf collimator

                   *  Balancing weights such as tungsten sinker bar, heavy metal boring bar,vessels crank camshafts, holders for well logging, racing weights, vibration damping and dynamic balancing weights

                  *  Substitutional material for Uranium

                  *  Electroheat upsetting anvil block

                  *  Balls in bomb

                  *   High voltage electrical contact

                  *  Electrodes for Resistance Welding

3.Product Standard:

                   * ASTM B 777-07

MMM offers two series of Tungsten Heavy Alloys: W-Ni-Fe(magnetic) and W-Ni-Cu(nonmagnetic).
