Mill Products

Back to the Future: Olin Brass Mill Products

While Olin Brass is a major player in virtually every industry where copper alloys are utilized, our core business remains centered in East Alton, Illinois, and the brass mill Franklin Olin founded nearly a century ago. Today, it’s among the most productive facilities of its kind in the world, capable of turning out well over a million pounds of finished product – copper alloys in coil form – every working day. Those alloys, in turn – 60 in all, from high coppers and brasses to phosphor bronzes and nickel silvers – form the foundation of the Olin Brass product portfolio.
