Elmet is a leading global provider of high quality molybdenum rod products and the only US producer of pure, swaged tungsten and molybdenum rod.
We offer a large range of standard rod diameters ranging from .030″ to over 1.0″ that can be cut to size to customer specified thickness, length and surface finish. We also offer precision machining, threaded rod and gun-drilled molybdenum rod. As with all of our materials, our rod begins as metal powder, pressed into ingots, sintered, and then swaged and drawn down. Our advanced drawing / swaging process enables us to tailor the product to meet specific customer material and performance requirements to ensure optimal performance in your application.

Fully Integrated Tungsten and Molybdenum Rod Manufacturing:
When tungsten and molybdenum material characteristics and properties must be critically controlled for superior end product performance, companies rely on Elmet Technologies unmatched expertise in the field of powder metallurgy. Our advanced powder processing produces pure tungsten and molybdenum metal powders as well as specific metal alloys. By selectively influencing aspects of the metallurgical process, we can change characteristics like porosity, strength, and temperature resistance to meet our customers specific needs. At Elmet, our process is fully integrated and starts with the raw material, metal oxide, which is then purified to tungsten and molybdenum metal powder through a chemical reduction process. The powder is formed into semi-finished products through a series of advanced mixing, pressing, deformation and heating technologies. Finished products are then carefully manufactured to customer specifications utilizing our state-of-the-art machining and fabrication techniques. By controlling each step in the production process from metal powder to finished product we ensures that our products consistently deliver the performance and quality required by our customers.
Precision Machining, Fabrication & Assembly:
Elmet also offers precision tungsten and molybdenum machining and fabrication capabilities. We’ve honed our processes during our decades of successfully working with molybdenum and tungsten. At our United States facilities, Elmet operates more than 70 machines that are dedicated to supporting your precision machining and fabrication requirements for molybdenum and tungsten.
