The Elmet Group Co. is a specialized manufacturing company that produces precision-engineered components and advanced high-energy systems for critical applications. Headquartered in Portland, Maine, the company operates through two primary business divisions: Critical Materials Components (CMC) and Engineered Microwave Products (EMP). The CMC division is a vertically integrated manufacturer of refractory metals, providing critical materials such as pure tungsten, molybdenum, niobium, tantalum, and specialized alloys. These materials are essential for extreme environments and high-performance applications. The EMP division focuses on designing and manufacturing high-power specialized radio frequency (RF) and microwave components and systems, including waveguides, circulators, loads, pressure windows, and automatic tuning systems.
Elmet's products are utilized across a diverse array of interconnected, high-growth markets, including aerospace, defense and government, industrial processing, medical devices, semiconductor fabrication, and energy (such as fusion research). By maintaining vertically integrated and scaled operations in the United States, the company positions itself as a crucial domestic supplier for the U.S. critical materials and components supply chain, supporting national initiatives in defense fortification and supply chain reshoring. The company generates revenue through the sale of these highly engineered components and systems to original equipment manufacturers (OEMs) and tier-one suppliers. The Elmet Group was formed through the combination of underlying entities including Elmet Technologies LLC and Microwave Techniques LLC, and the current holding company was incorporated in 2024 before completing its initial public offering on the Nasdaq in April 2026.
