Aluminum Manufacturing Companies in Illinois

Illinois has approximately 13,000 manufacturing establishments and 570,000 manufacturing employees. Illinois is a top-five manufacturing state, with Chicago as a metal fabrication and food processing center, Peoria as Caterpillar's headquarters, and a vast network of industrial suppliers.

Illinois contributes to the national aluminum manufacturing landscape. Aluminum manufacturing includes primary smelting, secondary recycling, rolling, extrusion, casting, and finishing of aluminum products. While US primary aluminum production has declined, secondary aluminum production from recycled scrap and downstream operations including rolling mills, extrusion presses, and fabrication facilities remain a major manufacturing sector.

Aluminum Rolling Mills: Operations producing flat-rolled aluminum sheet, plate, and foil for automotive, aerospace, packaging, and building applications.

Aluminum Extrusion Companies: Companies operating extrusion presses to produce aluminum profiles, bars, and tubing for construction and industrial use.

Secondary Smelters: Recycling operations that melt aluminum scrap to produce alloy ingots and billets for manufacturing.

Aluminum Castings Producers: Companies producing sand, permanent mold, and die cast aluminum components for automotive and industrial applications.

Major industrial centers in Illinois include Chicago, Rockford, Peoria, Aurora, Joliet, and Elgin. These cities have concentrations of manufacturers across sectors including metal fabrication, food processing manufacturing, and chemical manufacturing.
