ASTM Standard Tungsten Heavy Alloy Rods GMW Alloy 1.0mm to 100mm For Balance Rod

Tungsten Heavy Alloys (WHAs) are tungsten alloys that typically contain 90 to 98 wt% W. Most commercial tungsten alloys are two-phase structures, the principal phase being nearly pure tungsten in association with a binder phase containing the transition metals plus dissolved tungsten. As a consequence, WHAs derives their fundamental properties from those of the principal tungsten phase, which provides for both high density and high elastic stiffness. It is these two properties that give rise to must applications for this family of materials.

 
The current uses of tungsten heavy alloy (WHAs) are spanning a wide range of consumer, industrial, and government applications

Brief Introduction of Tungsten Heavy Alloy Rods:

Code: GMW
Density: (17-18.5) g/cm3
Main Component: W (88-98)% with the addition of nickel and copper or nickel and iron, etc.

Diameter: 1.0mm to 100mm

Length: Max 600mm

Surface Condition: Machined, Ground

Advantages of Tungsten Alloy Rods:

-High density
-Excellent mechanical properties such as high vibration-damping capacity and high Young's modulus.
-Excellent radiation-shielding property
-High thermal conductivity with low thermal expansion coefficient

Applications of Tungsten Heavy Alloy:

·  Protection shields for nuclear radiation such as PET syringe shield, vial shield, 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
