AMS2471, BPS B580, MIL-PRF-8625, PCD-130 & SS8483
WHY CHOOSE US FOR YOUR SULFURIC ACID ANODIZING NEEDS?
Erie Plating Company delivers controlled color anodizing on aluminum, enhancing visual appearance while maintaining the protective performance of the anodic coating.
We are NADCAP accredited for this process.
Erie Plating Company has developed a NADCAP-accredited sulfuric acid anodizing process, including specialized electrochemical treatments, that produce a thin aluminum oxide film to preserve and protect aerospace, military, and industrial aluminum components.
We also offer chromic acid anodizing, a thinner anodic coating process commonly specified for aerospace and military applications where fatigue resistance, dimensional stability, and minimal material buildup are critical.

Benefit
Dyed Sulfuric Acid Anodizing with Color provides the same corrosion and abrasion resistance as standard anodizing while offering functional color coding for part identification, traceability, and quality control.
Dyed finishes help reduce handling errors, simplify inspection, and preserve anodic coating performance. Black is the most commonly specified color due to its stability and broad acceptance across aerospace and industrial applications.
