NAICS 331314: Secondary Smelting and Alloying of Aluminum

NAICS 331314 – Secondary Smelting and Alloying of Aluminum covers the recovery, refining, and reprocessing of scrap and used aluminum into primary aluminum ingots, billets, and master alloys for industrial use. This sector plays a critical role in the circular economy of non-ferrous metals, employing pyrometallurgical processes such as melting, fluxing, degassing, and alloying to restore material purity and meet aerospace, defense, and transportation specifications. In government contracting, this NAICS supports the supply chain for high-integrity aluminum components used in military aircraft, naval vessels, and ground vehicle systems, where material consistency and traceability are paramount. The work often requires compliance with military specifications such as MIL-DTL-5580 and ASTM B211, and contractors must maintain rigorous quality assurance systems aligned with AS9100 or ISO 9001 standards. No contractor data is available for this NAICS code, indicating limited visibility of prime contractors or subcontractors in public award records. The competitive landscape likely includes specialized non-ferrous metal recyclers, alloy producers, and vertically integrated metal processors, some of which may operate under classified or indirect supply arrangements with defense primes. No agency data is available, but demand is presumed to originate from defense and aerospace procurement channels, particularly within the Department of Defense, NASA, and the Department of Energy, where lightweight, high-strength aluminum alloys are essential for platform performance and fuel efficiency. The market presents niche opportunities for certified metal recyclers and alloy developers with proven capabilities in controlled atmosphere melting, chemical analysis, and material certification. While procurement activity may be low in volume, it is high in strategic importance, with long-term contracts often tied to secure supply chains for critical defense materials.
