About The Elmet Group
The Elmet Group Co. (NASDAQ: ELMT) is a US-based provider of critical materials, precision-manufactured components and high-energy systems for aerospace, defense, industrial, medical technology, semiconductor/electronics and energy applications. The group is organized into three divisions: Critical Materials Components (CMC) as the only US-owned, vertically integrated manufacturer of pure tungsten and molybdenum, Engineered Microwave Products (EMP) for high-power microwave components and RF engineering, and Elmet Refining & Trading (ERT) for the sourcing, refining and supply of tungsten. The value chain extends from metal powder production through pressing and sintering, arc melting, extrusion, rolling, wire drawing and thermomechanical processing to precision machining, fabrication and additive manufacturing. In addition to pure metals, specialty alloys such as TZM, C103 and potassium-doped tungsten are processed. The headquarters is located in Portland, Maine; CMC manufacturing comprises three plants in Maine, Ohio and Michigan with over 500,000 square feet of floor space. The group supplies more than 100 US defense programs and over 95 programs of national laboratories as well as customers worldwide.
