6K Additive and Congressman Reschenthaler Promote Domestic Production of Critical Refractory Metals

Congressman Guy Reschenthaler Visits 6K Additive in Pennsylvania

On April 13, 2026, Congressman Guy Reschenthaler (PA-14) visited 6K Additive, Inc., a prominent player in the American production of high-quality metal powders. This event took place at their Burgettstown facility and was aimed at emphasizing the vital need for a robust domestic supply chain for critical refractory metals, which are essential for both national security and the progress of clean energy.

As global tensions rise and supply chains face vulnerabilities, 6K Additive leverages its state-of-the-art UniMelt® microwave plasma technology to manufacture high-performance materials like tungsten, rhenium, tantalum, and niobium/C-103. These refractory metals are crucial for high-temperature and high-strength applications across multiple sectors, including:

- Defense and Aerospace: Key components for hypersonic flight surfaces, missile parts, and vehicle armor.
- Energy Infrastructure: Materials necessary for advanced nuclear reactors and efficient power generation.
- Strategic Manufacturing: Domestic production of unique alloys aimed at reducing dependency on foreign sources.

Congressman Reschenthaler stated, "As a member of the House Appropriations Committee, I am dedicated to partnering with Pennsylvania's manufacturers to bolster the defense sector. 6K Additive's pioneering technology not only creates enduring jobs for local families but also fortifies our workforce. Their innovations are crucial for retaining top talent in our area. The materials produced here are fundamental for America’s competitive edge and security."

Frank Roberts, CEO of 6K Additive, echoed the Congressman’s sentiments, noting that the visit represents the confluence of Pennsylvania’s rich industrial legacy and the future of defense technology in the United States. "Our goal is to ensure that the U.S. no longer depends on dubious foreign sources for materials that are vital for the safety of our service members and energy security," he added.

During the visit, Congressman Reschenthaler got a firsthand look at 6K Additive's unique processes, which can transform solid waste materials, turnings, and defunct components into premium metal powders for additive manufacturing. This
