What is chromating?

September 25, 2024

Chromating is a surface treatment process for aluminum in which a thin conversion layer is applied. This layer protects the metal from corrosion, maintains electrical conductivity and improves adhesion for subsequent coatings such as paint or powder coating.

Yes, chromated surfaces are ideal for the Further processing suitable - in fact, this is one of its main functions. The conversion layer improves the Adhesive properties of the metal surface and thus creates a Ideal base for painting, powder coating or adhesive bonding.

The chromate layer ensures that coatings adhere evenly and do not peel off under thermal or mechanical stress. Especially for components that are to be painted or coated, chromating is a proven standard in industrial pre-treatment - efficient, material-saving and reliable.

Chromating creates a very thin, conductive protective layer, while anodizing creates a thicker, non-conductive oxide layer. Chromating is particularly suitable when good electrical conductivity or paint pre-treatment is required. Anodizing offers particularly high corrosion protection and a wide range of colour options.
