Aluminium anodic oxidation since 1964

Aluminium anodising is a process with a dual anti-corrosion and aesthetic function which electro-chemically converts the surface layer of the metal into oxide.
That layer may be of variable thickness depending on the applications:

from 5 to 10 microns for internal applications;
from 15 to 20 microns for external applications;
from 20 to 25 microns for industrial and marine environments, where the action of atmospheric agents is particularly aggressive.

However, thickness is not the only factor able to influence the properties and performance of anodised aluminium. The following also contribute:

concentration of sulphuric acid in the electrolyte;
electrolyte temperature;
applied voltage;
current density;
effectiveness of agitation with air.

The process of aluminium oxidation performed by Oxidal Bagno is perfectly in line with the parameters required by the QUALANOD quality label and by the corresponding European standards.
