TAM 1000 (90W Ni Cu)

Tungsten Alloy

TAM 1000 Tungsten Alloy

A 90% pure tungsten alloy with additions of nickel and copper.

Radiation Shielding

TAM 1000 (90W-Ni-Cu) is a tungsten alloy, typically used in radiation shielding and tooling. Tungsten offers numerous unique product advantages. It is a high-density alloy which is 65% denser than lead and 130% denser than steel alloys. TAM 1000 contains 90% tungsten, 6% nickel and 4% copper. The product offers superior shielding against x-rays and gamma rays and is 1.5 times more effective than lead. With such high density and high strength TAM 1000 also finds use in static balancing.


TAM 1000 provides greater resistance to acids when compared to stainless steels, so the alloy is suitable for use in hostile environments. The introduction of nickel and copper improves the ductility and machinability of the alloy.

Typical Applications

Commercial applications for this engineering material include:

  • Radiation shielding
  • Static balancing
  • Tooling

We stock TAM 1000 in round bar.
