Type I Anodize

Chromic Acid Anodizing

Type I anodizing, also known as chromic acid anodizing, creates a thin, dense, and highly corrosion-resistant oxide layer on aluminum surfaces. Type I produces a uniform, non-conductive coating that maintains part integrity while serving as an excellent base for primers, paints, and adhesives. This process is essential for aerospace, military, and high-precision applications, where dimensional tolerances and durability are critical.
