Chromic Acid Anodizing

Anodized Aircraft Parts

Chromic Acid Anodize is the accelerated oxidation of an aluminum surface. The natural thin oxide layer on aluminum prevents some corrosion. The layer can be thickened by the Chromic Acid Anodizing process. This alteration provides even greater scratch and corrosion protection.
