The Type I Chem Film Process

Like other types of chem film, type I chemical conversion coating uses a chemical solution to alter the surface characteristics of aluminum and aluminum alloys. After cleaning and etching the work surface, type I chem film uses a chemical composition that includes hexavalent chromium. This film typically appears gold in appearance, but it may be clear depending on the specific composition and the chem film process.
