Contact Corrosion Protection

Contact Corrosion Protection

Connections between Aluminum/Magnesium and Steel

• With connections between aluminum or magnesium and steel, the corrosion protection measures described below must be observed. At attachment points between aluminum and steel or magnesium and steel:

• Fender

• Front hood

• Doors

• You must use protective foil on rear lid.

• When bolting aluminum or magnesium to steel, you may only use Dacromet-coated screws which may only be used one time. Dacromet is a green, chemical protective coating that prevents contact corrosion.

• Non-metallic fastening or sealing elements (door seals, rear lid seal) between two different metals should not be electrically conductive.

• You can find special notes about the procedure in the corresponding repair groups in the repair manuals.
