What Aurora Metals does

Aurora Metals Division, LLC is a U.S. precision casting job shop that produces custom non-leaded brass, bronze, aluminum bronze, and stainless-steel alloy components. Its manufacturing stack rests on four core processes: vacuum die casting, vacuum permanent mold for impellers, permanent mold casting, and air-set sand foundry casting, with an all-electric induction furnace for metallurgical control and tolerances documented at ±0.005 inches under 1 inch with 125 RMS surface finish. The 2024 addition of 3D printed sand molds and cores adds a toolless prototyping and complex-geometry layer to the traditional casting flow. The company operates from a single 100,000 sq ft facility in Montgomery, Illinois, with 100+ employees, and sells through a direct, sales-led model with project-based quoting (no public pricing).

The company's largest end-market is the centrifugal pump industry, where it supplies impellers, valve bodies, and related safety-critical components to fire pump, fire truck pump, wastewater, cryogenic, and agricultural pump manufacturers. Secondary applications include aerospace/defense parts, marine hardware, electrical connectors, and other industrial uses where porosity-free, near-net-shape castings reduce secondary machining. Aurora Metals holds ISO 9001:2015 certification and has continuously operated since its 1899 founding; it is privately held with no disclosed parent company, investors, or institutional capital events.

Core offering

Aurora Metals operates a precision casting job shop that produces custom non-leaded brass, bronze, stainless, and duplex alloy components via vacuum die casting, permanent mold casting, and sand foundry casting, with its largest segment being vacuum cast impellers for centrifugal pumps. The company complements these processes with 3D sand printing for rapid prototyping and complex geometries, and supplies a portfolio of standard silicon brass/bronze and aluminum bronze alloys, primarily serving OEMs in fire pumps, fire truck pumps, wastewater, cryogenic, and agricultural pump markets from its 100,000 sq ft Montgomery, Illinois facility.

Product overview

Aurora Metals Division, LLC is a precision casting company offering a comprehensive suite of manufacturing services built around four core casting processes: Vacuum Die Casting, Vacuum Cast Impellers, Permanent Mold Casting, and Sand Foundry Casting. These are complemented by an additive manufacturing capability (3D Printed Sand Molds and Cores) and a portfolio of Standard Alloys (copper-based silicon bronzes/brasses and aluminum bronzes). The company operates from a 100,000 square foot facility in Montgomery, Illinois with over 100 employees and serves primarily the centrifugal pump industry, along with fire safety, wastewater treatment, chemical processing, marine, agricultural, and general industrial sectors.

Functional benefit

Products and services

• Vacuum Die Casting Specialty vacuum die casting process for non-leaded brass and bronze alloys, producing high-density, porosity-free castings ideal for critical applications including pump impellers, valve bodies, and aerospace components.
• Vacuum Cast Impellers Precision geometrically consistent impellers for the centrifugal pump market, produced using proprietary vacuum casting process with metal vacuum die and metal core equipment in straight blade or Francis blade designs.
• Permanent Mold Casting Permanent mold casting technique for brass and bronze alloys delivering consistent, high-quality castings with superior surface finish (125 RMS), tight tolerances (+/- .005" for dimensions less than 1"), and excellent mechanical properties from an all-electric induction furnace.
• Sand Foundry Casting Air-set sand foundry casting services for stainless steel, duplex stainless, super duplex stainless alloys, cast iron, and non-leaded brass/bronze alloys, accommodating casting weights from 2 to 250 pounds and production quantities of 1 to 500 pieces per month.
• 3D Printed Sand Molds and Cores Additive manufacturing capability for producing 3D printed sand molds and cores directly from digital files, enabling toolless production, rapid prototyping, complex geometries, and consolidated assemblies for customers across various industries.
• Standard Alloys Range of non-leaded copper-based casting alloys including Silicon Bronze/Brass (C87500, C87600) and Aluminum Bronzes (C95300, C95400, C95500, C95800), supplied with detailed mechanical and physical property specifications.
