Quelques explications techniques

Rohde already has a nearly 60-year tradition of surface treatment on high-quality precision goods made of aluminium and its alloys. Here, anodizing with or without dyeing is by far the most popular form of protection against corrosion.

Produit de précision pour l'industrie optique

Basically, the colour anodizing on parts of this kind and of the types on the following pages 32-36 is used in manually-operated machineries.

Produit de précision pour la technique orthopédique

As already highlighted on the reverse side, these articles can only be processed to a high quality on manually-operated machinery, too.

Composants pour centrifugeuses de laboratoire

Components of this kind in a wide variety of versions rank among the most precise and expensive individual parts in a centrifuge.

Produit de grande distribution en vrac

Small bulk goods of aluminium, which are not stackable (e.g. rivets, screws, lathe-cut parts) can be anodized as "loose goods” in a similar manner like at barrel galvanizing.

Grandes séries de petites pièces

As far as it is technically possible or justifiable, articles like the aluminium stampings illustrated here can be anodized in large quantities simultaneously.

Extrudé; éléments de construction et de facade

For quality reasons, anodized aluminium sections, pre-treated by grinding, brushing or polishing, are still used today, especially in interior finishing work. Due to the diverse shapes of these sections, a lot of manual work requiring specialist experience is involved.

Anodisation du titane

The electrolytic production of an oxide layer on titanium and titanium alloys is done in accordance with the international standard for aerospace (Specification LN 29747).
