Hard Anodizing

Through an electrochemical process it is possible to provide aluminium parts with an oxide layer. This layer of 10 to 100µm goes 50% into the surface and ensures a 50% increase of the surface. Typical hardness is 400HV. Because an oxide is formed, this layer is electrically insulating.
