CAO: Chromic anodic oxidation
The BF5 process is covered by a patent and a trademark registered by SGI; it is a chromic anodizing process which is characterized by its simplicity and reliability of use.
Electrolytic conversion treatment applicable on aluminium alloys; its characteristics are as follows:
These chromic anodizing lines satisfy aeronautical specifications perfectly and are certified by most customers: AIRBUS France, Alenia, Boeing helicopters, British Aerospace, CASA, Dassault Aviation, Dornier, Fabrique Federale d’Emmen, Gamesa, SAAB, SABCA, SNECMA, SONACA, Pratt & Whitney (Canada), etc.
BF5 chromic anodizing is used for primary parts constituting aircraft fuselages and in precision engineering. It is also useful as temporary protection and receipt inspection of plate intended for the aeronautical industry. Finally, it can create savings in the event of subsequent hard anodizing.
New development.... Class III sealing
A new sealing process has been developed and patented in collaboration with Dassault Aviation. This process provides both high corrosion resistance of the anodizing and optimum adhesion of the paint system.
