Specification by standards

  • ISO 7599
  • DIN 17611
  • STN EN 2284
  • MIL-A-8625
  • DEF STAN 09-25

Advantages of clear aluminium anodizing:

  • pollution and corrosion resistance
  • high wear resistance and UV resistance
  • electrical non-conductivity
  • possibility of additional coloring of the layer that does not change the dimensions of the part and obtains a stable uniform shade

Types:

  • Non-colored - anodized layer has a silver-gray tint that is finely toned according to the alloy used.
  • Black anodized – anodized coating is additionally dyed with black organic paint.
  • Electrolytically colored - anodized layer is electrolytically colored to C1-C35 - colors from gray to bronze and black.
  • INOX color - anodized layer colored to the final appearance as stainless steel.
