Chemical conversion – chrome-free

Chromium-free conversion

Conversion without chrome is a pre-treatment method used especially for aluminum and galvanised items.

This method provides good adhesion for subsequent paints and inhibits under-corrosion.

The items are most often in die-cast, sand-cast or die-cast aluminium as well as aluminium items, plates and other metals such as magnesium.

We can convert items of 2,000 x 750 x 1,400 mm and with an item weight of up to 450 kg.
