ANODISING

Anodising offers attractive possiblilties for optical designs providing at the same time excellent corrision resistance. Layers which are normally used are 10 to 25 µm thick. Basically all common aluminium alloys can be anodised.

But if high optical demands have to be met the use of alloys specially suitable for anodising is to be recommended. Alloys containing copper may show a yellow shade of color, components containing high silicon a grey tone. This has to be considered when choosing the material.
