Protective treatment applicable only on aluminium and its alloys.

Because of the electrochemical converting of the raw aluminium surface to aluminium mixed oxides, it protects the treated items against the corrosive agents warranting them to last for long term under adverse conditions.

The corrosion-proof is depending by the oxides thickness which growth is penetrating.

Hence the treatment avoids increasing the product dimensions which are guaranteed independently from the oxides amount.

The minimum film thickness has 3 microns.

Optional: black or brown colouring, lubrication with white oil solution, previous sand-blasting to get the surface more homogeneous.

Being the film insulating the anodic oxidation affects the products’ electric features.
