Aluminum is used more and more today due to the reasonable cost, ease of machining and light weight. The only negative issue that arises with aluminum is the limited metal finishing options. Unlike stainless steels, you cannot passivate aluminum in order to remove the contaminants on the surface. In addition, there are few options for improving microfinish after machining. Electropolishing is an effective means for providing a part that has an enhanced surface finish and clean surface. Many companies use the electropolishing for parts that are assembled in a clean room, such as laser components.

At Able Electropolishing, we perform our signature electropolishing treatment on a variety of metal alloys, including aluminum. Following our treatment, parts have an enhanced corrosion resistance, improved microfinish, and are clean and free of harmful contaminants. Along with the commonly used 6061 aluminum, our process is suitable with other alloys such as 1100, 3003, 5002 and 7075.

Contact us to see how we can utilize our metal finishing capabilities for your aluminum parts.
