NAICS 331529 - Other Nonferrous Metal Foundries (except Die-Casting)
This page includes content generated by AI. It is intended for general guidance only and should be verified for your specific situation.
What is NAICS 331529
NAICS code 331529 covers establishments primarily engaged in pouring molten nonferrous metals—excluding aluminum—into molds to produce nonferrous castings. This sector includes foundries specializing in metals such as copper, nickel, lead, and zinc, creating cast components for various industrial and manufacturing applications. Businesses operating within this classification focus on precision casting techniques, excluding die-casting processes, and provide essential metal components used in sectors ranging from aerospace to infrastructure.
Government agencies contract these services to procure durable, high-quality metal parts critical for defense, transportation, and infrastructure projects. The specialized nature of nonferrous metal foundries ensures that government projects receive components that meet stringent material, performance, and durability standards. This industry is vital to supporting government supply chains with customized metal castings that cannot be sourced through off-the-shelf materials.
