Mill products

Back to the future: Our Mill products

While Wieland Rolled Products NA is a major player in virtually every industry where copper alloys are utilized, our core business remains centered in East Alton, Illinois, and the Wieland Rolled Products NA mill products 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 our product portfolio.
