Secondary Smelting and Alloying of Aluminum
NAICS 331314 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in (1) recovering aluminum and aluminum alloys from scrap and/or dross (i.e., secondary smelting) and making billet or ingot (except by rolling) and/or (2) manufacturing alloys, powder, paste, or flake from purchased aluminum.
Start the review with fire and explosion.
For Secondary Smelting and Alloying of Aluminum, the saved research highlights fire and explosion, environmental/pollution liability, employee injury. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What is the primary feedstock — post-consumer scrap, industrial scrap, dross, or purchased aluminum — and what quality controls are in place for incoming materials?
- What type and number of furnaces are in operation, and what is the approximate annual throughput in tons?
- How is dross and salt flux waste managed, stored, and disposed of, and what is the current regulatory compliance status?
- Are any aluminum powders, pastes, or flakes manufactured on-site, and what dust explosion prevention controls are in place?
- What is the full loss history for the past five years, including any fire, explosion, environmental, or products incidents?
- For Secondary Smelting and Alloying of Aluminum, what should the underwriter know about prior fire, explosion, or molten metal incident losses?
- For Secondary Smelting and Alloying of Aluminum, what should the underwriter know about open environmental violations, pending regulatory actions, or unresolved dross waste disposal liabilities?
- For Secondary Smelting and Alloying of Aluminum, what should the underwriter know about aluminum dust or powder manufacturing without documented explosion prevention controls (bonding, grounding, dust collection)?

Secondary aluminum smelters recover aluminum and aluminum alloys from scrap metal, used beverage cans, dross, and industrial waste through high-temperature melting furnaces, then cast the refined metal into billets, ingots, or other forms. Some operations also manufacture aluminum alloys, powder, paste, or flake from purchased aluminum feedstock. Facilities typically involve rotary or reverberatory furnaces, flux treatment, casting lines, and significant materials handling of both scrap inputs and finished metal products.
