Manufacturer of Bronze Alloy Castings

Erie Bronze and Aluminum is a trusted bronze casting company that alloys a wide range of bronze alloys in-house. Our non-leaded bronze castings are made to serve industries ranging from plumbing goods manufacturers to Defense contractors. On this page you can develop an understanding of our bronze casting capabilities. Some of our most popular non-leaded bronze castings include aluminum bronze, manganese bronze, tin bronze, and silicon bronze. Our castings can meet a diverse variety of specs ranging from those set out by ASME, ASTM, a range of Mil-Specs, and more. To ensure our castings match these specifications precisely, we utilize a SPECTROLAB metal analyzer to complement our experienced team’s alloying capabilities.

Bronze Castings

Aluminum Bronze Castings (952, 953, 954, 955, 958)

Some of our most popular work as a bronze casting company involves pouring aluminum bronze alloys. We can pour 952, 953, 954 aluminum bronze, and more. These aluminum bronze alloys are wear resistant and exhibit good welding characteristics as well as exceptional mechanical properties. They withstand corrosion in many environments including seawater, chlorides, and dilute acids. These alloys are considered non-sparking and suitable for equipment designed to handle explosives, petroleum, chemical and gas products. Aluminum bronze alloys containing more than 10% aluminum can be heat treated to boost their mechanical properties for environments that are expected to generate greater wear and impact on the alloy. If you need one of these popular aluminum bronze alloys poured, contract EBA as your bronze casting company.

Manganese Bronze Castings (862, 863, 865)

When customers contract Erie Bronze in need of our strongest cast copper alloys, they choose Manganese Bronze. We can pour 862, 863, and 865 manganese bronze at our foundry. These castings are used primarily for heavy duty mechanical products requiring moderately good corrosion resistance. In addition to their wear resistance, our manganese bronze castings can be poured at a reasonable cost, making them an especially strong option for heavy duty environments. These alloys not only have high tensile and yield strength but can operate under very high loads and speeds which makes them a great alloy for your bearing needs. If you want to learn more about the benefits of Manganese Bronze, contact EBA for a discussion. Alternatively, if your spec sheet requires one of these three castings, request a quote now.

Tin Bronze Castings (903, 905, 907, 911)

Tin bronze alloys are known for providing reasonable corrosion resistance, moderately high strength, good wear resistance, and a lower coefficient of friction compared to steel. They are capable of accepting shock and impact loads, but with reduced surface speeds which makes them an excellent choice for high strength bushing and bearing applications as well as moveable bridge components. We can pour 903, 905, 907 Tin Bronze, and more at EBA. Our Tin Bronze Castings can be alloyed in accordance with the SAE 620 spec, also known as Navy G Bronze. If your equipment requires a low friction coefficient while also providing corrosion resistance and durability, our Tin Bronze Castings may be the ideal solution and you can contact us for a quote today.

Silicon Bronze Castings (873, 875)

Silicon Bronze is intended to provide a moderate strength casting, which will exhibit good corrosion resistance when submerged in liquids or chemicals. Applications range from bearings and gears to plumbing goods and intricately shaped pump and valve component manufacturing. Our casting company alloys 873 and 875 silicon bronze in-house, and we have the equipment needed to test our alloys to ensure they meet the spec(s) your job calls for. If you have a valve component or a pump with a complex shape that is going to be in a corrosion exposed environment, Silicon Bronze may serve as the ideal casting to contract our team to provide.

Proprietary Processes

Our proprietary degassing and static casting processes eliminate trapped gasses from the molten metal and assure uniform distribution of alloys throughout the entire casting process. All metals are alloyed and tested in-house using an optical emission spectrometry (OES) Spectrometer. Optional test bars and chemistry reports are available to meet the customer’s QS and ISO requirements.
