Copper Casting Foundry Serving the United States

Copper casting foundry team and facility

Copper is chosen when conductivity, corrosion resistance, and reliability matter. The key is partnering with a copper casting foundry that can control the process so your parts pour clean, finish well, and perform the way the spec expects.

Buffalo Metal Casting has produced non-ferrous castings and finished components since 1975, supporting customers across the United States as a single-source supplier from pattern to shipped part.

What "Single-Source Copper Casting Foundry" Means Here

One accountable supplier: casting, machining, inspection, and secondary operations coordinated under one roof.
Less rework downstream: controlled molding and pouring practices that help parts machine and finish predictably.
Fewer vendors to manage: one quote, one schedule, one team that owns the outcome.

Why Copper Gets Spec'd

Copper castings show up in demanding environments where performance is non-negotiable.

Electrical and thermal conductivity for power, grounding, and heat-transfer applications
Corrosion resistance in moisture, marine, and chemical-adjacent conditions
Durability for long service life and high reliability expectations
Machinability for critical fits, sealing faces, and functional surfaces

Copper Casting Processes Built Around Your Part

We match the process to your geometry, tolerance expectations, finish requirements, and run size.

Permanent Mold Copper Casting

Reusable metal tooling for repeat production and consistent results across runs.

Best for: recurring parts, stable dimensions, long-term cost control.

Green Sand Copper Casting

Cost-effective molding for small to medium parts where practicality matters.

Best for: production-friendly shapes, balanced cost, dependable output.

No-Bake (Air-Set) Copper Sand Casting

Reliable method for medium to larger parts with improved finish and accuracy.

Best for: larger parts, complex cores, higher surface-finish expectations.

Precision Shell Sand Copper Casting

Superior finish and dimensional accuracy for small to medium parts.

Best for: tighter requirements, cleaner surfaces, fine detail.

Automated Flaskless Matchplate Molding

Automated green sand molding for repeatability and detailed production work.

Best for: repeat orders, consistent output, detailed features.

Quality and Inspection That Protect Your Downstream Work

When copper parts go into electrical, thermal, or corrosion-exposed applications, rejects are expensive. Our Quality Assurance Plan is built to reduce rework with documented procedures and inspection support.

ISO-aligned quality planning with documented tests and inspections
Inspection and testing support for customer specifications
Non-destructive testing options: X-ray, penetrant, pressure testing
Physical and chemical analysis available when required

Value-Added Services That Turn a Casting Into a Finished Part

If you need finished components, not just raw castings, we support ready-for-use requirements with services that keep quality and timing under control.

Engineering assistance and casting layout support
Pattern-making and production tooling construction
In-house heat treating
CNC machining (vertical milling centers and lathe work)
Finishing: plating, painting
Heli-arc welding and assembly

Typical Copper Foundry Work We Support

Electrical components, grounding parts, and conductive hardware
