Tungsten MACHINING & FABRICATION
With 90 years of experience and formerly as part of the Royal Philips group, Elmet is a global leader in Tungsten refractory metal machining and fabrication. As technologies advance, component and assembly specifications become more stringent; machining and fabrication techniques must support demanding precision requirements and increasingly complex geometries.
At Elmet Technologies, we pride ourselves in offering our customers sophisticated tungsten and molybdenum machining and fabrication capabilities that have been honed over decades of experience with two of the most challenging materials to machine: molybdenum and tungsten. We operate more than 70 machines dedicated to supporting your precision machining and fabrication requirements. Below is a brief list of some of our current capabilities.

Examples of Fabricated Parts
Many high-temperature industrial furnaces use molybdenum (moly) components for elements, element supports, power terminators, and process fixtures. Hot Isostatic Press (HIP) construction requires shells fabricated from molybdenum sheets. These are used to support the heating elements, and may also act as shielding. Likewise, flat heating elements made from molybdenum sheet are used in vacuum and hydrogen furnaces.
Ion Implant Semiconductor Tool Parts
Silicon wafer processing relies on the use of ion implantation systems that inject ions at high energy directly into silicon wafer surfaces. The ion plasma source is energized via tungsten electrodes which operate within fabricated tungsten arc chambers.
The use of molybdenum as leads and supports and the use of core tungsten components have long been central to the success of the lighting industry. Cut, welded and formed molybdenum and tungsten wire and rod parts are essential for the production of economical glass-to-metal sealed parts in lamp construction. For certain high-intensity discharge lamps, anodes and cathodes are machined from molybdenum and tungsten rod.
Sintering Boats and Carriers
Elmet has industry-leading expertise and experience in the precision machining, forming, and fabrication of molybdenum sintering boats and carriers. Leading companies purchase Elmet-made boats, carriers and other fabrications for a diverse array of applications including nuclear fuel sintering, evaporative deposition, and high-temperature furnace.
