Our Story

Over a Century of Bronze & Aluminum Casting

Founded in Neenah, Wisconsin in 1906, we have grown from a small local foundry into one of the region's most trusted names in non-ferrous casting — while never losing sight of our roots as a family business built on craftsmanship.

From a Small Shop to a Century-Strong Institution

What started in 1906 as a small bronze casting operation in Neenah, Wisconsin has evolved into a full-service non-ferrous foundry serving customers across the United States. Through two World Wars, economic cycles, and generations of change, we've remained committed to one thing: delivering exceptional castings on time, to spec, every time.

Our facility houses modern sand casting lines, permanent mold capabilities, and a full CNC machining shop — giving us the rare ability to take a project from raw pattern to finished, machined part all under one roof. That level of vertical integration means tighter tolerances, faster lead times, and a single point of accountability for our customers.

As the foundry evolved and expanded, it has rebranded to Neenah Bronze and Aluminum Foundry, reflecting both our geographic roots and the breadth of our material expertise. Whether you need manganese bronze marine propeller components, architectural aluminum panels, or silicon bronze decorative elements — we have the alloy expertise and casting craftsmanship to deliver.
