Black anodizing
A black aluminium surface to EN and MIL standards. The dye sits directly in the anodic layer, without lacquer.

Black anodizing is an anodic layer dyed black. The dye is deposited in the pores of the aluminium oxide and sealed in them.
We offer black anodizing to EN and MIL standards. On clear anodizing we dye with an organic black dye; with hard anodizing and castings, black evens out the shade that the alloy would otherwise determine. It is not lacquer; the colour is part of the layer, so it does not peel off. We process black-anodized parts in a tank measuring 3200 × 1650 × 800 mm.

The colour is part of the layer and does not peel off like lacquer.
It evens out the shade of hard anodizing and of castings.
Why choose black anodizing
Find out in 30 seconds whether black anodizing is the right choice for your part. If you are not sure, send us a drawing. A technician will assess it and suggest a suitable treatment.
The standard prescribes black anodizing
Your specification requires black anodizing to EN or MIL. We perform it to both.
Uniform look across different alloys
Parts made of different alloys would have a different shade after anodizing. Black evens it out, both in hard anodizing and for castings.
Black without lacquer
You do not want a coating that can peel off. The black dye sits in the pores of the anodic layer and is sealed in.
Results you
can measure
We do not give verbal ratings; we give measurable figures you can verify on your part.

min. layer on a casting
We hard anodize die castings with a special process, usually with a layer of min. 20 µm. Black then evens out their otherwise uneven shade.

No. Lacquer is a layer applied to the surface; black anodizing is a dye deposited in the pores of the anodic layer and sealed in. That is why it does not peel off.
Yes. In hard anodizing, black evens out the shade that is otherwise determined by the alloy, from pale grey through olive green to dark brown.
Yes. For die castings we have a special hard anodic oxidation process with a layer of min. 20 µm, and by dyeing them black we even out their otherwise uneven shade.
