Aluminum Manufacturing Companies in California

California has approximately 35,000 manufacturing establishments and 1,300,000 manufacturing employees. California is the largest manufacturing state by output, leading in aerospace, semiconductors, medical devices, and food processing across its diverse regional economies.

California is one of the leading states for aluminum manufacturing. 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 California include Los Angeles, San Diego, San Jose, San Francisco, Fresno, Irvine, and Long Beach. These cities have concentrations of manufacturers across sectors including semiconductor manufacturing, aerospace manufacturing, and medical device manufacturing.
