This table presents detailed information on U.S. companies engaged in the processing of tungsten, highlighting the specific intermediate and powder products they manufacture. This data is crucial for understanding the domestic tungsten supply chain, which supports key industries such as aerospace, defense, electronics, and manufacturing. Tracking the types and locations of tungsten processing facilities helps gauge the nation’s capacity to produce critical materials, assess supply chain resilience, and inform economic and industrial policy decisions related to mineral resources.
In 2021, the U.S. tungsten processing industry was characterized by a diverse range of products and a concentration of facilities in several states. Global Tungsten & Powders Corp., located in Towanda, PA, stood out as a major processor, producing ammonium paratungstate, ammonium metatungstate, tungsten oxides, metal powders, and carbide powders, reflecting a broad product portfolio. Niagara Refining LLC in Depew, NY, also contributed significantly with ammonium paratungstate and tungsten oxides production. Notably, Buffalo Tungsten Inc., also in Depew, focused on tungsten metal and carbide powders, while Kennametal Inc. operated two plants in Fallon, NV, and Huntsville, AL, specializing in carbide powders. The presence of Chem-Met Co. in Clinton, MD, producing calcium and sodium tungstates, indicates ongoing activity in intermediate product manufacturing. Overall, the data suggests a stable but specialized industry with key players maintaining diverse production capabilities across multiple states.
