6K Additive, Inc.

6K Additive, Inc., a self-certified small disadvantaged business manufacturer based in Burgettstown, Pennsylvania, produces spherical metal powders and advanced alloy materials for defense and aerospace industrial base development, operating primarily as a prime contractor (56% of recent awards) on federal R&D and production contracts with secondary subcontract work in specialized powder supply.

6K Additive competes under total small business set-asides on its higher-value work and in full-and-open procurements for specialized material deliveries. The company's recent prime awards include a $3.9 million SBIR Phase II definitive contract from the Defense Logistics Agency (awarded March 2026, completion October 2027) for the "Grave to Cradle" initiative—recovering, reclaiming, and converting critical metals from defense and industrial scrap into spherical alloy powders and ingots; a $1.86 million fixed-price definitive contract from DLA (awarded April 2025, completion May 2026) to convert domestic titanium C-103 niobium into spherical alloy powders and ingots for aerospace bearing supply chain resilience; and a $75,537 purchase order from the Army Materiel Command Research Development and Engineering Command (awarded May 2025, completion May 2025) for 420 kilograms of spherical tungsten powder. 6K Additive also holds a $7.5 million Blanket Purchase Agreement with Army RDECOM, active through July 2028, for metal products and additive manufacturing services. Additionally, the company is a recipient of a $47.3 million Defense Production Act Title III cooperative agreement from the Office of the Secretary of Defense (awarded December 2023, completion July 2027) focused on upcycling waste and scrap materials into critical materials for national defense.

Customer concentration leans toward defense industrial base modernization. The top funding agencies by potential value are the Army Materiel Command Research Development and Engineering Command ($7.6 million across 2 awards), DLA Troop Support ($3.9 million), DLA Headquarters ($1.9 million), and the Department of Energy National Nuclear Security Administration (2 awards). The Department of the Air Force appears on both the award-count and potential-value lists. Combined obligated dollars ($53.1 million) exceed combined potential value ($13.3 million) by 298 percent, indicating substantial work execution beyond contract ceilings or multiple modifications to base awards.

In its subcontractor role, 6K Additive supplies specialized powders to Fluor Marine Propulsion for Naval Nuclear Laboratory and Naval Nuclear Propulsion Program powder procurement (two awards dated March 2026) and delivers titanium alloy material to University of Oklahoma under a sustainment and modernization research contract (award October 2025, $42,800 order for 250 kilograms of TI-64 GD23 powder at 45 microns). The company also subcontracts to Consolidated Nuclear Security for Y-12 National Security Complex operations support (award May 2024).

Activity has accelerated—one award in 2024 to three in 2025 and three in 2026 to date—with two awards (combined potential value $3.9 million) reaching ultimate completion within the next twenty-four months, exposing those vehicles to recompete. Work sits primarily under NAICS 541512 (Research and Development in Physical, Engineering, and Life Sciences) and defense-related experimental development PSC codes. 6K Additive's capability footprint centers on spherical alloy powder production via selective laser melting and additive manufacturing techniques, critical metal recovery and conversion from scrap, and advanced material supply for aerospace and naval nuclear propulsion programs.
