Calumet Brass Foundry

Calumet Brass Foundry (CalBrass) is a fourth-generation, family-owned American foundry specializing in high-quality brass and bronze castings, custom guide services, and a robust supply of bar stock — proudly melted and manufactured entirely in the U.S. since 1906. For over a century, we’ve built our reputation on trust, respect, and craftsmanship. Today, we continue to serve industries that keep North America running: steel mills, mining operations, energy infrastructure, OEMs, and industrial equipment repair and resale. We pour copper-based alloys to meet demanding specifications and maintain the capacity to cast up to 3,550 lbs. With more than patterns on hand and the ability to create new custom patterns, we deliver solutions tailored to unique production needs. Beyond castings, CalBrass is a trusted partner for custom guide services used in rolling mill operations and similar heavy industry processes — from a few ounces to over 2,200 lbs per guide. Our extensive bar stock inventory in various brass and bronze alloys means we can quickly supply raw material or pre-cut pieces to meet urgent demands. When breakdowns happen, downtime costs more than money — that’s why our emergency services are ready 24/7. Many jobs can be cast, finished, and shipped within 24–48 hours to get customers back up and running fast. At CalBrass, we stand by American-made quality and responsive, expert service — qualities that have earned us customer relationships lasting decades.
