Black Semi-Hard Anodizing
Black Semi-Hard Anodizing or anodization allows obtaining all the features of semi-hard oxidation and the aesthetic characteristics of black oxide coloration.
- Moderate growth of the superficial roughness
- Consistent increase of superficial hardness (>350 HV₀₀₅ according to internal specification)
- 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.
Black Semi- hard oxidation generally applies to 1000, 5000, 6000, 7000 alloys.
