Hard Anodising

DETAILS

Anodising – Hard Anodising

Hard anodising is typically 25 to 50µm thick and used for providing wear resistance where surface contact loads are light, for instance in the low stress abrasive wear caused by food or pharmaceutical products. It is also be used for corrosion protection and thermal or electrical insulation.

Hard anodising can be combined with polymers for a wider range of low friction and non-stick applications. More information on these coatings can be found on our Apticote 350 page.

Poeton’s Hard anodising, irrespective of the type, benefits from the following advantages:

  • Fully automated lines
  • Accurately controlled chemistry and maintenance
  • Low noise, automated ramping power supplies
  • Professional Laboratory back up onsite
  • Highly trained and skilled operators
  • Comprehensive quality inspection

These levels of controls and automation allow Poeton’s hard anodising to have a more uniform structure, improving the hardness and ability to be honed.

For advanced hard anodising see Apticote 300 and for Hard Anodising combined with polymers see Apticote 350.
