6K Additive showcases US refractory metal powder production

6K Additive, Inc has reported a recent visit by US Congressman Guy Reschenthaler to its Burgettstown, Pennsylvania, USA, facility, highlighting the importance of establishing a US domestic supply chain for refractory metal powders and specialised alloys.

As global tensions rise and supply chains for critical minerals remain vulnerable, the company is leveraging its proprietary UniMelt microwave plasma technology to produce high-performance materials such as tungsten, rhenium, tantalum, and niobium alloy C-103.
These refractory metals are used in high-temperature and high-strength applications across a variety of sectors. In defence and aerospace, such materials are used in hypersonic flight surfaces, missile components, and vehicle armour. In energy and infrastructure, they support advanced nuclear reactors and high-efficiency power generation systems.

During the visit, Congressman Reschenthaler observed the company’s production process, which converts solid scrap, turnings, and end-of-life components into metal powders for Additive Manufacturing. This circular approach is intended to strengthen supply chain security while reducing environmental impact compared to traditional mining and refining methods.
6K Additive also noted that, rather than relying on overseas supply chains, it offers a fully domestic solution aimed at ensuring material sovereignty for critical defence and energy applications.

“6K Additive is leading the way in cutting-edge technology while creating family-sustaining jobs for hardworking Pennsylvanians and strengthening our local workforce,” stated Reschenthaler. “Their innovation is helping attract and retain critical talent in our region. From hypersonics to nuclear energy, the materials produced in Burgettstown are keeping America competitive and secure.”
The visit follows a series of developments for the company, including defence-related contracts and the expansion of its Burgettstown facility to meet growing demand for specialised metal powders in the Additive Manufacturing sector.
