Item No.: 031
WNiFe tungsten alloy sphere has many advantages over conventional balance materials such as steel or lead, thus make it an ideal material of counterweights in Aerospace fields.
Tungsten Heavy Alloy Sphere Aerospace Counterweight
Advantages of tungsten alloy sphere:
- High density up to 18.5 g/cm3.
- Up to 65% denser than Lead.
- Up to 130% denser than Steel.
- Mechanical properties to suit either dynamic or static locations.
- Weakly Ferro magnetic.
- Non-magnetic, if specifically required.
- Alternative to Lead.
- Non-Toxic.
- Corrosion resistant.
- Easily machined.
- Easily mechanically joined, brazed or shrunk fit to other materials.
