Process of the line

Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. Aluminum alloys are anodized to increase corrosion resistance, to increase surface hardness, and to allow dyeing (coloring), improved lubrication, or improved adhesion. Chromic acid anodizing, Sulfuric acid anodizing, Tartaric Sulphuric anodizing and Phosphoric acid anodizing are among examples of different anodizing solutions made possible by Galvatek plants.
