Buy tungsten heavy metal (DensM)

High-density tungsten heavy alloys for balancing, radiation shielding and vibration damping.

Browse products

Tungsten heavy metals (DensM) are sintered alloys with very high density. They are used for balancing weights, radiation shielding, vibration damping and applications where a lot of mass is needed in a small space. Machinable and easy to work. Common grades are W90NiFe and W92.5NiFe (in stock as DensM 170 and DensM 175); higher densities such as W95NiFe and W97NiFe and the non-magnetic WNiCu variant are available on request.

Frequently asked questions about tungsten heavy metal

Which tungsten heavy alloy grades does Molytun offer?

We supply the common WNiFe grades to ASTM B777: W90NiFe (approx. 90 % tungsten, ~17.0 g/cm³) and W92.5NiFe (approx. 92.5 % W, ~17.5 g/cm³) from stock as DensM 170 and DensM 175. Higher densities such as W95NiFe (~18.0 g/cm³) and W97NiFe (~18.5 g/cm³) and the non-magnetic WNiCu variant (e.g. W90NiCu) are available on request.

What is the difference between WNiFe and WNiCu?

WNiFe (nickel-iron matrix) is mechanically stronger and more economical, but magnetic. WNiCu (nickel-copper matrix) is non-magnetic and therefore the right choice when magnetism interferes — e.g. in measurement and sensor technology. Both reach comparable densities.

Why tungsten heavy metal instead of lead?

DensM is significantly denser than lead, non-toxic and machinable — ideal where maximum mass or shielding is required in a small space.

Can DensM be machined?

Yes, tungsten heavy metal can be machined (turning, milling, drilling).
