Industries that Demand an Aluminum Castings Supplier
With decades of hands-on manufacturing experience, Erie Bronze & Aluminum understands how precision aluminum castings are expected to perform in demanding environments. Our team regularly produces components like labyrinth seals, bearing housings, and other machined parts that must deliver exceptional reliability. Labyrinth seals, for example, are engineered to create a winding path that minimizes fluid or gas leakage in compressors, turbines, and pumps. Bearing housings protect bearings and ensure stable performance, while precision-machined bearings themselves reduce friction and maintain consistent motion in mechanical systems.
As a trusted aluminum castings supplier, we produce parts that meet exacting customer specifications, whether rough-machined with enough stock to ensure precise final dimensions or supplied as the raw, unmachined log for quick turnaround times. Erie Bronze & Aluminum supplies rough-machined aluminum tubes and rings to your required dimensions to help cut down on your machining requirements. The three aluminum alloys we produce in our foundry are 850, 852, and 443. These alloys possess excellent qualities for labyrinth seals and bearings, in addition to impressive compressive yield strengths and superior lubricity and machinability compared to other materials, such as plastics and AL6061.
Our castings are widely used in the compressor industry, but our work spans far beyond into other auxiliary or supporting industries, such as:
- Oil and gas production, including offshore and refinery operations
- Chemical processing plants that require corrosion-resistant components
- Naval and marine applications exposed to saltwater conditions
- Cryogenic refrigeration systems for industrial and scientific use
- Robotics and automation, where lightweight strength is critical
- Additive manufacturing projects needing custom-fit components
Our aluminum castings are also a critical aspect to help power and protect equipment across countless demanding applications, including:
- HVAC and climate control systems
- Hydraulic systems in heavy equipment
- Electric motors for industrial and consumer products
- Engines, pistons, and precision mechanical assemblies
- Pumps, valves, and flow control systems
When choosing an American aluminum castings supplier, industry experience and knowledge of quality standards matter. Erie Bronze & Aluminum combines metallurgical knowledge, precision machining, and a proven track record of meeting standards across diverse applications to ensure every casting delivers reliable, long-term performance.
Manufacturer of Aluminum Castings to ISO & ITAR Standards
Erie Bronze & Aluminum’s metals are alloyed and tested in-house using our SPECTROLAB metal analyzer to meet the customer’s various quality standards, along with ITAR and ISO requirements. We can test the specific chemistry makeup of every ladle we pour, which allows us to cut costs by alloying the material in-house instead of purchasing an ingot. Generally, Erie Bronze & Aluminum’s rough-machined aluminum castings are manufactured within the specifications below, but custom dimensions can be produced:
| Outer Diameter (O.D.) Range (in) | Outer Diameter (O.D.) Range (mm) | Maximum Length (in) | Maximum Length (mm) |
| Up to 8.0 | 190.5 – 127.0 | 13 | 330.2 |
| 8.0– 17.5 | 254.0 – 444.5 | 16 | 406.4 |
| 17.5 – 21.0 | 381.0 – 533.4 | 12.5 | 317.5 |
| 21 – 27.0 | 508.0 – 685.8 | 7 | 177.8 |
| 27 – 37.5 | 762.0 – 952.5 | 5* | 127.0 |
We can customize the outside diameter, inside diameter, and overall length of our rough-machined aluminum castings to meet customer specifications. Our proprietary casting process and technology help eliminate trapped gases from the molten metal and assure uniform distribution of tin throughout the entire aluminum casting process.
A few advantages of this automated process include:
- Reduced gas porosity
- Improved surface finish
- Reduction of hard inclusions
- Increased tensile strength
- Reduced machining costs
- Consistent mechanical and physical properties
