Type I Chromic Acid Anodize

Type I Chromic Acid Anodize Services for Manufacturers

Type I Anodizing, also called Chromic Acid Anodize, is a common anodizing technique that creates an oxide layer on the surface of the metal substrate.

The thinnest of the three main anodic coating processes, Chromic Acid Anodize delivers an electrically non-conductive surface with improved scratch and corrosion resistance.

Because the resultant oxide layer is so thin, Chromic Acid Type I Anodize is the preferred process for aerospace and other industrial components that may undergo flexing due to heat changes or mechanical means.
