Product Description

Kefeng's Tungsten Balance Weights (Tungsten Counterbalances or Tungsten Counterweights) are made from the tungsten heavy alloy, it can be used to compensate for oscillations, weight transfers, imbalances and vibrations, create or shift centers of gravity and more generally ensure the optimum balance.  Our tungsten weights can be made by WNiFe and WNiCu tungsten alloys and we supply tungsten balance weights, counterbalances and ballasts as per your drawing.  Tungsten balance weights are crucial components in many different applications and help to reduce the loads that parts are exposed to and consequently increase their service life:

- Aviation and aerospace: Propeller and rotor blades, Aircraft weights
- Automotive industry: Crankshaft counterweights/balancing and chassis weights, Vibration dampening governors, flywheels and turbines balance
- Watch industry: Bobs/weights on watch rotors
- Optical industry: Microscopes and measuring instruments

Tungsten Nickel Copper Alloy (WNiCu Alloy) Properties:

-High density (17-18.1g/cm3)
-High melting point
-Wear resistance
- High tensile strength
- Good elongation capacity
- Low vapor pressure
- Excellent thermal stability and High radiation absorption capacity
- Non-Magnetic

Thanks to these advantages, they are widely used in various fields including sports, industry and medicine etc. The most common high density Tungsten alloys are16.85~18.85g/cc for W-Ni-Fe alloy and W-Ni-Cu alloy.  We are capable in producing different kinds of tungsten heavy alloy products, we can also manufacture them according to clients' specifications.

Physical and mechanical properties of W-Ni-Cu Alloys:

Tungsten High Density Alloys
Tungsten-based alloy materials are outstanding due to their high density and exceptional mechanical properties characterized by ductility and hardness and whose high density is equaled only by gold, platinum, and a few other rare and expensive metals.  Tungsten alloys are exceptional for applications were maximum concentrated weight is required in the smallest possible space. The addition of chemical elements such as nickel, copper, and iron, creates a family of tungsten alloys with extremely useful properties for machining. These alloys are economically fabricated by powder metallurgy techniques and are routinely machined by conventional methods.  Tungsten alloys can be well processed both as semi-finished product for further processing by the customer or as per the customers' drawings as finished machined component. To meet the specific application of our customers we recommend the delivery of the finished machined product.

 

Our High Performance Tungsten Alloy  materials provide a solution in a wide range of applications requiring concentrated weight or density in a limited space. These lead-free parts meet legal requirements and recommendations to protect the environment.  Twice as heavy as steel and more than 50% heavier than lead, tungsten alloys have become an essential material for a wide variety of applications in aerospace, defense, medical, oil and gas exploration.
 

More Applications can be found in: Balance weights, radiation protection, vibration absorbers, heat transfer, drilling bars. The mechanical characteristics have to guarantee the stability and strength in any application case.  The absorption of x-ray and gamma radiation is in direct proportion to the density of the shielding materials.
