Manufacturer of Aluminum

Erie Bronze and Aluminum is the preferred aluminum casting supplier to manufacture rough machined castings for labyrinth seals, bearings, and bearing housings. EBA analyzes the chemistry of every heat poured and implores stringent processes to ensure the integrity of every part we cast.

EBA is the first US-based foundry to utilize a real time hydrogen Foundry Degassing Unit, the newest metal treatment and gas analyzing technology developed in Europe. Our proprietary casting process and degassing technology helps eliminate trapped gasses from the molten metal and assures uniform distribution of tin throughout the entire aluminum casting process.


Aluminum Supply

Erie Bronze & Aluminum’s metals are alloyed and tested on-site using our SPECTROLAB metal analyzer to meet the customer’s specification requirements. We test the chemistry of every ladle we pour, which allows us to use a variety of raw materials, keeping costs at a minimum.

Types & Applications of Alloys

We have spent decades refining our proprietary process for three hard -to -pour aluminum alloys: 850, 852, and 443. These alloys are commonly used to produce bearings, bearing housings, and labyrinth seals. These special aluminum alloys allow us to manufacture castings with superior machinability, bearing quality, compressive yield strength, and lubricity compared to parts made from other materials like plastics and AL6061.
