Semi-Hard Anodizing

DESCRIPTION

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.

CHARACTERISTICS

  • 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;
  • Dielectric;
  • Moderate thermic isolation.

WIDTHS

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

APPEARANCE

Multiple shades of light grey (according to aluminium alloy use and oxide width).

OXIDE ALLOYS

Semi-hard Oxidation applies to 1000, 5000, 6000, 7000.
