Black Semi-Hard Anodizing

DESCRIPTION

Black Semi-Hard Anodizing or anodization allows obtaining all the features of semi-hard oxidation and the aesthetic characteristics of black oxide coloration.

CHARACTERISTICS

  • 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;
  • Dielectric;
  • Moderate thermic isolation.

WIDTHS

From 15 to 35 µm according to initial alloy features and needs.

APPEARANCE

Black Colour.

OXIDE ALLOYS

Black Semi- hard oxidation generally applies to 1000, 5000, 6000, 7000 alloys.
