Custom Engineered Hard Anodize Services

Custom Electrolytic & Hard Anodizing Services FM Industries, Inc. anodizing process strengthens and protects Aluminum alloys by converting the Aluminum alloy surface to Aluminum oxide. Our process is completely traceable and repeatable with 60,000 data points collected per anodizing run. Working primarily with 5000- and 6000-series alloys, we can also accommodate custom alloys. Our electrolytic solutions include standard sulfuric acid, standard mixed acid, and custom multi-mixed acids.

Our rack tanks and fully automated system, including a robotic hoist, can handle parts up to 78” long, 24” wide, and 48” high. Parts can weigh up to 1,000 lb. Anodize film thicknesses up to 4 mils on 6000 series and 5 mils on 5000 series are available. All coatings are fully tested for thickness, abrasion resistance, and roughness and can meet HCL bubble test resistance of greater than 8 hours. Voltage breakdown can exceed 1000 V/mil.

FMI offers a chemical engineering staff that works with each individual client to develop an anodizing solution that is custom designed to each application. For more information on our custom electrolytic and hard anodizing services, please see the table below or contact us directly. We look forward to working with you.
