What this NAICS covers

NAICS 331529 covers production of nonferrous metal castings using foundry processes other than die-casting, including sand, shell, and investment casting of aluminum, brass, bronze, copper, and other nonferrous alloys for industrial components.

Federal opportunities under 331529 typically involve producing cast nonferrous parts to engineering drawings, pattern and core production, heat treatment and metallurgical testing, nondestructive inspection, and finishing steps to meet dimensional and material chemistry specifications.

FAQ

What work fits NAICS 331529?
  • Manufacturing sand- or shell-cast aluminum structural components and housings to drawing tolerances with required metallurgy certificates.
  • Producing bronze or copper valve bodies and pump components using investment or sand casting with subsequent heat treatment and machining allowances.
  • Supplying short-run replacement castings for legacy equipment with pattern development, coremaking, and fettling to drawing specifications.
  • Delivering metallurgical test reports, chemical composition certificates, and nondestructive inspection results (radiography or ultrasonic) for cast nonferrous parts.
When is NAICS 331529 a weak fit?
  • Die-casting operations - use high-pressure die-casting processes and permanent tooling rather than sand, shell, or investment foundry processes covered here.
  • Ferrous metal foundry work - production of iron or steel castings uses different materials and processes outside the nonferrous foundry scope.
  • Machining-only contracts - fabricating parts from bar or plate stock without molten metal casting, patternmaking, or foundry core production.
What solicitation language points to NAICS 331529?
  • Specification names casting processes such as sand, shell, or investment casting and requires pattern/core production deliverables.
  • Contract requires metallurgical testing, chemical analysis certificates, and nondestructive inspection reports for delivered castings.
  • Statement of work calls for castings supplied to drawing with heat-treatment records, machining allowances, and final dimensional inspection reports.
