Excellence in Tungsten

At M&I Materials we have over 40 years’ experience in the end to end production of tungsten alloys. We excel at turning powder into parts and precision machining tungsten alloys. As a result we can produce high quality tungsten components to very tight tolerances from a material which is notoriously difficult to machine.

Wolfmet is our range of composite materials containing tungsten particles in an alloy binder. By weight, our Wolfmet grades are 90-97% tungsten and therefore benefit from the unique density and radiation shielding capabilities of tungsten.

We supply Wolfmet in two ranges - magnetic (HE range) and non-magnetic (HA

Our experience and expertise help us to provide quality components and we also understand how important it is to deliver excellent service. When you buy Wolfmet from M&I Materials you can be certain of the following:

  • It is manufactured in the UK and we only use non-conflict sources
  • Our processes are ISO 9001, ISO 14001 and, for aerospace applications, AS9100 accredited
  • Support from experienced engineers who are able to provide guidance on manufacturability or innovative requirements
  • Access to a technical team of professionally qualified metallurgists
  • Flexibility - we can provide small runs of bespoke items, or large quantities for long production runs


Radiation Shielding

Wolfmet’s superior attenuation and density allows designers to reduce the thickness of shields / collimators whilst providing the same protection as lead.
