Aluminum chemical conversion coating (chrome-free and trivalent chromium) forms a dense inorganic film on the aluminum surface, greatly improving corrosion resistance. The resulting film has excellent adhesion with paint and adhesives, ensuring long-term durability. As an environmentally friendly alternative to conventional hexavalent chromium treatment, it is widely used in fields such as aerospace, transportation equipment, and electronics.
