Processes for treating aluminium


luminium surfaces, finished parts, semi-finished products as well as cast aluminium parts and forgings usually show soiling in the form of oxide layers, chips, polishing pastes, greases, separating oils or polishing residues due to the upstream processing – here the aluminium treatment helps.

In the process Washing-staining-preserving these surfaces are specifically optimized by applying a conversion layer. This passivation layer is ideally suited as a primer for subsequent painting, bonding, powder coating, KTL coatings and guarantees very good corrosion protection due to its adhesion-improving properties.

The anodizing (anodic oxidation) is an electrochemical process that converts the surface of aluminum into aluminum oxide. The resulting oxide layer is firmly bonded to the aluminum.
