Chem/Chromate Films have minimal electrical resistance, with slight variables between Class 1A and 3. Class 3 is the most electrically conductive of the two. Electrical resistance increases with the darkness of color.
“Chromating” is an economical replacement for anodizing when abrasion resistance is not needed. Aluminum parts achieve a higher corrosion resistance when Chem-Film is applied. Chem-Film, used as a post-plating process, provides an excellent paint adhesion and a superior base for bonding. Another important quality of this type is the ability to heal small scratches due to being soluble.
Chromate conversion leaves no measurable build-up, but provides excellent corrosion resistance. UPI’s process conforms to Mil-DTL-5541 and Mil-C-5541. Colors available are clear or gold. UPI of North Alabama has the capacity and qualifications to meet your production and delivery needs specifically in anodizing, chem film, and chromate conversion alodine.
