Chem Film Finishes North Alabama
Chromating is an economical replacement for anodizing when abrasion resistance is not required. Aluminum parts achieve a higher corrosion resistance when Chem-Film is applied. Used as a post-plating process, Chem-Film provides an excellent paint adhesion and an excellent base for bonding. Another important quality is the ability to heal small scratches due to being highly soluble.
Chem or Chromate Films have low electrical resistance, with slight variables between Class 1A and 3. Class 3 is the most electrically conductive of the two types. Electrical resistance increases with the darkness of color.
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. United Plating of North Alabama has the capacity and qualifications to meet your production and delivery needs specifically in anodizing, chem film, and chromate conversion.
