Treatments

Sulfuric anodic oxidation of Aluminium is a technology widely used to protect aluminium and its alloys, to improve mechanical performance like corrosion resistance and wear resistance or simply to improve aesthetics of this extraordinarily versatile metal.

We currently provide different types of anodising:

​

NATURAL ANODISING                                                 

Low thickness anodic oxidation (from 5 to 25 microns), generally used to protect surfaces from minimum corrosion and spontaneous oxidation.

​

SEMI–HARD WHITE ANODISING 

Thicker oxide layer with the possibility of keeping a light grey colour (from 25 to 35 microns). Generally used in the pharma and food industries.

​

HARD ANODISING

Typical surface treatment designed to improve the mechanical performance of the base material in every respect. In all of our three plants we provide low temperature hard anodising in order to guarantee high superficial hardness (from 30 to over 80 microns depending on the specific aluminium alloy).

​

G.H.A.® (Technical data)
Special anodic oxidation with Ag+ ions that confers extreme mechanical performances (anti-corrosion, anti-wear, antimicrobial and antistatic properties).

​

G.H.A.® BLACK

Black coloured anodising of average thickness and hardness but with remarkable antimicrobial properties.

​

PLUS®  

Proprietary hydrothermal treatment developed to maximize the corrosion resistance of every type of anodising we provide.
