Custom Bronze &
Aluminum Castings
Neenah Bronze & Aluminum Foundry has delivered precision non-ferrous sand castings from Neenah, Wisconsin since 1906. From complex architectural bronze to high-performance industrial aluminum components — custom cast and CNC machined to your exact specifications.
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.
Formerly known as Anchor Castings, Neenah Bronze & Aluminum Foundry is now in its second generation of family ownership in Neenah, Wisconsin. 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.

CNC Machining
In-house CNC machining capabilities let us finish your castings to tight tolerances without leaving our facility. From simple facing operations to complex 5-axis geometry, we handle the full spectrum.
Pattern Development
Our experienced pattern makers work from customer drawings, 3D models, or sample parts to create durable, dimensionally accurate patterns. We maintain a large library of existing patterns for repeat orders.
Alloy Expertise
Over a century of metallurgical experience across a broad range of non-ferrous alloys. From standard copper alloys to specialized aluminum formulations, we know our metals inside and out.
