Anodising

Reliable corrosion protection for aluminium.

Constituting the electrolytic oxidation of aluminium, anodising utilises an electrochemical process to generate a corrosion resistant coating on the surface of aluminium.

The essential properties at a glance

• excellent corrosion protection depending on coat thickness and aluminium alloy
• resistant to solvents, acids, and weak alkalis
• electrically insulating effects
• weather resistant
• optimal antifriction properties (hard anodic coating)
• standard and special colourability of anodic coating for decorative purposes
• permanent protection against wear and other external damaging effects
• suitable for cathodic dip painting and bonding agents

With optimal processes to the ideal surface

• DC sulphuric acid and DC sulphuric-oxalic acid processes
• standard anodising
• the combination of anodising and subsequent coating (powder, wet, or cathodic dip painting) enhances the corrosion resistance
• pretreatment with wet blasting gives rise to a look of particularly high quality
• anodising as a pretreatment generates a good keying surface for bonding agents
