TAM 3000 (90W Ni Fe)

Tungsten Alloy

TAM 3000 Tungsten Alloy

TAM 3000 is used in the production of balance weights for aerospace applications.

Dynamic Balancing

TAM 3000 (90W-Ni-Fe) is a tungsten alloy containing 7% nickel and 3% iron. With a density of 17.05 gm/cm³, TAM 3000 finds use in applications where dynamic balancing is a requirement. The product is particularly useful in aerospace and motorsport applications, due to the alloys high density, making it easy to add weight without using large volumes.


The alloy is slightly magnetic and provides a tensile strength of 70N/mm². With high strength and high resistance to thermal fatigue, TAM 3000 has numerous uses in engineering applications and is machinable to close tolerances.

Typical Applications

Commercial applications for this engineering material include:

  • Dynamic balancing
  • Balance weights
  • Blade weights
  • Anti-flutter weights and bucking bars

We stock TAM 3000 in round bar.
