Natural Anodizing or anodization creates a hard oxide through the flow of electricity according to specific parameters in tanks kept at room temperatures.
- Resistance to corrosion, from 8 to 72 hours according to oxide width, ref UNI 9227 norm;
- Moderate thermic isolation;
- Moderate increase of superficial hardness (300 HV₀₀₅ according to internal specification).
From 5 to 20 µm
Multiple shades of light grey (according to aluminium alloy use and oxide width).
Natural Oxidation can be realised on all aluminium alloys.
