TAM 3970

Tungsten Alloy

TAM 3970 Tungsten Alloy

TAM 3970 is ideal for applications where mass needs containment in a small space.

Weight Solutions

TAM 3970 (97W-Ni-Fe) is a tungsten alloy product containing 97% tungsten, 2.1% nickel and 09% iron. The alloy is slightly magnetic and has superior tensile strength (880N/mm²) when compared to TAM 1000, TAM 3000 and TAM 3950. The density of the material is even higher at 18.50 gm/cm³. The product is used as ballast and in balancing components. It is suitable for use in applications where a removable or permanent weight needs to be added to affect the centre of gravity. Aircraft, helicopters and the motorsport sector all make use of tungsten products in this way.

Thermal Fatigue

TAM 3970 also benefits from high resistance to thermal fatigue.

Typical Applications

Commercial applications for this engineering material include:

  • Ballast
  • Balance weights
  • For applications where mass needs containment in
  • a small space

We stock TAM 3970 in round bar.
