Hard anodization is a non-chromic electrolyte treatment that guarantees very high resistance against corrosion of acid and basic agents. Such treatment involves, through the passage of current according to certain parameters in the tubs, the formation of hard oxide.
Its applications are many, starting from the automotive field as standard and for competitions, to the aerospace, packaging, pharmaceutical, textile, food, cycling and many other uses.
The thickness of the treatment varies from 20 to 60 degrees depending on the starting alloy and needs and gives properties such as:
Important increase in surface hardness (>500 HV” according to UNI 7796 Standard);
Corrosion resistance (336 hours in sadial fog according to UNI ISO 6227 on alloy 6063);
Increased resistance to wear and surface abrasion;
Stability in light > 3000 h UV Electricity;
Moderate thermal insulation.
