    Description:

     

    Tungsten heavy alloys which can also be called high gravity alloys are refractory metals, it is a kind of alloy using tungsten as matrix and components nickel, iron, copper and other alloying elements. Basically there are two series, W-Ni-Fe and W-Ni-Cu, sometimes even W-Ni-Cu-Fe. 

     

    Our tungsten alloy cube are produced by powder metal and sintering processes.Tungsten is the world's 4th heaviest metal.Tungsten heavy alloy contains mainly tungsten ranging from 80wt% to 98wt%, and its density can reach 15.8~18.5g/cm3. Nickel, iron, copper serve as binder between tungsten grains and make the material ductile and more machinable. Compared to W-Ni-Cu, W-Ni-Fe possesses a better mechanical property, being widely used in national defense industry.

     

    Tungsten heavy alloys have many special properties such as high density (15.8-18.5g/cm3), high melting point, wear resistance, high tensile strength, good elongation capacity, low vapor pressure, excellent thermal stability and high radiation absorption capacity, etc., so due to these advantages they are widely used in various fields including the military, sports, aerospace, aviation, oil drilling, electrical instrumentation and medical industries.

     

    Our processing route for tungsten heavy alloys is show in Figure 1. Firstly, mix the calculated amount of elemental powders according to certain ratio, ball milling to even all powders and refine powder grains. Then, employ cold pressing and liquid phase sintering to almost full density. The matrix alloy melts and some tungsten dissolves into solution during liquid phase processing, resulting in a microstructure through which large tungsten grains (20–60µm) are dispersed in the matrix alloy. The as-sintered material often is subjected to certain aging treatments, finally leading to improved strength and hardness in the heavy alloys.

    Applications:

     

    Tungsten heavy alloy has a series of excellent physical, chemical and mechanical properties, so it is widely used for the balance weight and military industry.

     

     

    Advantages of tungsten heavy alloy:

     

    The most outstanding property of heavy metal alloys is the high density, which is far higher than nickel, titanium and lead alloys. It is employed to be a substitute for those alloys, not only because of its superior physical properties mentioned above, but a low expansion coefficient and high modulus of elasticity. Its ray absorption capability is 30~40% higher than lead, the thermal conductivity is five times than die steel.
