What this NAICS covers

NAICS 331524 covers metalworking facilities that cast aluminum parts by sand casting, investment casting, permanent-mold, and other non-die-casting methods, producing finished or semi-finished aluminum castings for industrial, structural, and equipment use.

Federal opportunities under 331524 typically involve production contracts for aluminum castings including pattern and mold fabrication, coremaking, melt and pour operations, fettling and heat treating to specified metallurgy and dimensional tolerances, and inspection and certification to drawing requirements.

FAQ

What work fits NAICS 331524?
  • Produce sand-cast aluminum housings and structural castings to drawing tolerances, including pattern fabrication, coremaking, gating, and finishing to specified metallurgy.
  • Supply permanent-mold aluminum castings with required heat treatment and chemical composition certification for repair and replacement parts.
  • Provide prototype and low-volume investment-cast aluminum components with pattern shop support, first-article inspection, and material certifications.
  • Perform fettling, gating removal, dimensional inspection, and delivery of raw or semi-finished aluminum castings for downstream machining under a production order.
When is NAICS 331524 a weak fit?
  • Die-casting operations - missing high-pressure die-casting equipment and processes used for high-volume, thin-walled castings produced by die casting.
  • Wrought and forging manufacturers - missing forging, rolling, extrusion, or continuous casting and subsequent wrought-product operations rather than mold-based casting.
  • Contract machine shops that only machine purchased castings - missing primary casting operations such as melting, molding, and core production that define foundry work.
What solicitation language points to NAICS 331524?
  • Line items controlled by drawing and specifying casting method (sand, permanent-mold, investment), part weight, gating/riser allowances, and acceptable porosity levels.
  • Quality requirements listing chemical composition certificates, heat-treatment records, nondestructive inspection (X-ray or magnetic particle), and first-article inspection reports.
  • Requests for vendor capability details such as pattern shop capacity, coremaking methods, melt capacity, and applicable environmental permits and certifications.
