Process of electropolishing+passivation

The electropolishing process involves the removal of a limited amount of material from the outer layer of the brass or copper item, to remove surface imperfections, contaminants, sharp edges, cracks and micro-perforations that contribute to corroding the item. 

The surface that is obtained with electropolishing is smooth, highly resistant to corrosion and free from imperfections that could compromise the strength and longevity of the material. Adding to the process, Alticolor offers passivation treatment involving immersion that gives an item additional protection against corrosion.

Alticolor treatments undergo rigorous control procedures
resulting in certification to guarantee the quality
of the process management.
