Product description

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. A great number of preparatory treatment techniques, such as fine-grinding, brushing, polishing, glass-blasting, vibratory grinding and satin-finishing provides in normal cases a decorative surface quality to meet the highest standards.

General information:
In anodizing processes, as opposed to lacquer coating and galvanized protection or decorative layers, there is no application of a foreign layer on the surface of the article. In anodizing, the aluminium surface is changed into an aluminium oxide which is microporous and can therefore be dyed.
As anodized finishes do not have a spreading and levelling effect, slight scratches and damages are visible after anodizing. For this reason a mechanical surface treatment or the more budget-price dull finishing is usually done beforehand; both processes entail a certain amount of material abrasion.
