Chicago Bronze opened its doors in 1980 with a simple mission: make buying bronze parts straightforward. We started as a small shop serving local machine builders and shipyards, supplying sleeves, rings and bar that were cast right and delivered when promised. Over the years we focused on what customers told us they valued most—clear communication, predictable lead times, and practical help choosing alloys.

Today we supply centrifugal sleeves and continuous-cast bar in the bronzes you actually use—nickel aluminum, manganese, tin/leaded, aluminum, and spinodal (C72900 class)—delivered as-cast or rough-machined with finish allowance left. To save time on both sides, we built buyer-friendly tools: pick an alloy, compare key properties, and see an LME-linked indicative price in minutes. Then send the drawing and we’ll confirm manufacturability, delivery, and documents. No guessing, no run-around—just straight answers and parts that show up on time.
