About the company
Sigma Aerospace Metals LLC, based in Ronkonkoma, New York, supplies specialty aerospace aluminum and metal materials (sheet, plate, bar stock, and extrusions) to the Department of Defense as a prime contractor on a full-and-open basis, with minimal subcontract exposure. The company operates as a limited liability partnership structured for profit and competes without small business set-asides across its federal footprint.
Sigma's customer base concentrates heavily on Navy aviation and logistics customers. The Naval Air Systems Command accounts for 140 of 163 prime awards (97% of award count) carrying a combined potential value of $193 thousand, while the Naval Air Warfare Center (a Naval Air Systems Command component) holds six awards worth $3 million in combined potential value — a split that reflects a much larger potential value in a smaller number of orders from the Warfare Center. The Special Operations Command, Naval Supply Systems Command, and Defense Logistics Agency Aviation round out the active customer set across ten distinct agencies. All six subcontract awards route through primes: Bell Textron on a Future Vertical Lift platform development order for aluminum plate (June 2025) and Lockheed Martin on multiple AC-130J retrofit kit and aircraft material orders (2022–2023).
Sigma's concrete work centers on non-ferrous metals wholesale and manufacturing. The top NAICS categories are Aluminum Sheet, Plate, and Foil Manufacturing (52 awards), Metal Service Centers and Other Metal Merchant Wholesalers (33 awards), and Aluminum Extruded Product Manufacturing (16 awards). Supply classifications are equally concrete: Bars and Rods (60 awards), Plate/Sheet/Strip/Foil in nonferrous base metals (26 awards), and Pipe, Tube, and Rigid Tubing (21 awards). Recent named prime work includes a $3,381 purchase order from Navy Aviation (December 2025) for AMS5862 15-5PH material in 0.5-inch plate, a $7,631 order for metal bar stock (August 2022), and a 4-by-12-foot sheet order in AMS4315 material (November 2022). Activity has been episodic: 34 awards in 2013, one in 2015, three in 2022, four in 2023, and two in 2025. The combined potential value across 169 awards totals $3.2 million, with only $324 thousand obligated to date (10% realization), indicating order-by-order transactional purchasing rather than standing contract vehicles. Sigma sits on two indefinite delivery contracts — H9225417D0001 and N6833510A0023 — with five task orders each, the latter carrying $26 thousand in combined potential value.
