Colored Dyes For Chromate Conversion Coatings

As with anodized finishes, chromate conversion coatings can also be dyed bright colors for decorative/esthetic purposes. 

Coloration is accomplished by simple immersion of the alodined part followed by a water rinse and an air dry. 

This simple process provides a very economical means of providing a decorative and corrosion-resistant finish on aluminum parts.
