With a chemical reaction of controlled oxidation, we transform alloy’s surface from an instable state (rough or dull material) to a stable state (metal with a layer of protective oxide).

The oxidation treatment, associated with silk-screen printing process, allow the penetration of colored pigments in the oxidized layer, achieving great chromate results, particularly resistant over time.

This procedure is particularly recommended when the completed product come into contact very type of hot or cold chemical solvent, oils, fatties, etc. Therefore is suitable for the employment in mechanical, electromechanical and electronic industries.
