The Semi-Hard Anodizing or anodization creates a hard oxide through the flow of electricity according to specific parameters in tanks kept at pre-defined temperatures.
- Slight increase of superficial roughness;
- Consistent increase of superficial hardness (>350 HV₀₀₅ according to internal specifications);
- Resistance to corrosion;
- Increased resistance to wear and tear and abrasion;
- Moderate thermic isolation.
From 15 to 35 µm according to initial alloy features and needs.
Multiple shades of light grey (according to aluminium alloy use and oxide width).
Semi-hard Oxidation applies to 1000, 5000, 6000, 7000.
