Chrome-free chemical conversion coating for aluminum and aluminum alloys - zirconium treatment.
This is a treatment that provides excellent corrosion resistance while improving adhesion.
High corrosion-resistant chemical treatment for aluminum. The zirconium treatment generates a chemical conversion coating on the surface of aluminum and aluminum alloys, such as A1100, A2017, and A5052, using zirconium compounds, thereby providing excellent corrosion resistance and improving the adhesion between aluminum alloys and paint films as a primer. Unlike treatments using trivalent chromium compounds, there is no risk of generating hexavalent chromium compounds due to heating or aging. 【Features】 ○ Colorless coating → Treatment can be performed without changing the appearance after processing ○ Does not contain chromium compounds in the coating ○ No risk of generating hexavalent chromium compounds due to heating or aging ○ Chemical treatment compliant with environmental regulations ○ Good paint adhesion ○ Almost no change in the dimensions of the material → Etching may be necessary if thick oxide films, altered layers, or release agent layers are formed ○ Applicable to precision parts For more details, please contact us or refer to the catalog.
