Aluminum Manufacturing Companies in Idaho

Idaho has approximately 1,800 manufacturing establishments and 68,000 manufacturing employees. Idaho's manufacturing sector is anchored by Micron Technology's semiconductor operations in Boise and a significant food processing industry.

Idaho 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 Idaho include Boise, Nampa, Meridian, and Idaho Falls. These cities have concentrations of manufacturers across sectors including semiconductor manufacturing, food processing manufacturing, and wood products manufacturing.
