Olin Brass (now Wieland East Alton)

Historic U.S. copper and brass strip producer; the East Alton, Illinois plant (originally opened 1916) was the flagship facility of Olin Corporation's Brass Division until Wieland acquired it and rebranded it Wieland Rolled Products NA. Wieland announced a $500M modernization in January 2024 to replace the century-old hot rolling equipment with a new hot mill, cold mill, and automated high-bay storage — targeting EV connector strip, bus bars, and specialty alloys. Olin Corp (NYSE: OLN) now operates primarily as a chlor-alkali chemicals and ammunition company after selling its brass operations. The East Alton site has ~800 retained employees. The PMX Industries subsidiary in Iowa (formerly Olin's) was separately retained and serves as a separate U.S. connector strip rolling operation with ~120,000 MT/year capacity.
