TUNGSTEN ALLOY

 

Specializing in High Quality Heavy Metal Alloys

 

Tungsten heavy alloys are ideal for high-density applications or for use in radiation shielding.Heavy metal tungsten alloys are 90% to 97% pure tungsten in a matrix of nickel and copper or nickel and iron. The addition of these alloying elements improves both the ductility and machinability of these alloys over non-alloyed tungsten.

 

We supply alloy as:

  • rod
  • bar
  • plate
  • Sheet
  • Finish machined parts and assemblies

As we produce material on site we can provide short lead times.

Custom Alloy Machined Parts

MGS specialise in a “one stop shop” approach supplying not just material but also finish machined parts to customer drawings and specifications. As suppliers to the majority of F1 teams for their ballast requirements we are used to dealing with short lead time requirements in one of the most time critical industries.

As suppliers to key aircraft programmes both for fixed wing and rotor craft we work to the most stringent aerospace requirements including NADCAP approved NDT and painting were required.

As suppliers into some of the most demanding and well known scientific projects including CERN, the JET fusion project as well as many others MGS are proud to play our part in supporting new developments in science and industry.

As suppliers into the developing world of nuclear medicine, security scanners and oil well logging, MGS have supplied many of the collimators, isotope containers and syringe shields and shielding used by the leading developers, both academic and commercial in these fields.
