Increases the performance of components with treatment that eliminates all surface imperfections, increasing the aesthetic and anti-corrosion properties of the item.

4 benefits in 1 process

Thanks to combined action on many fronts, electropolishing aluminium improves the natural resistance to corrosion of the alloy.

  • 01.

    Deburring operation that eliminates surface micro-imperfections that could affect the performance of the item.

  • 02.

    Microfinishing operation to remove material from the thickness or diameter of an item, improving its roughness. 

  • 03.

    Ultracleaning operation to remove residue and other contaminants and produce a bright surface.

  • 04.

    Finally, the aluminium electropolishing process increases its resistance to corrosion.
    The electrolyte basically removes the outer layer of the metal, thereby eliminating micro-imperfections from the surface which could give rise to corrosion.

Benefits of electropolishing

  • 01.

    Uniform finish

  • 02.

    Improves quality of surface aesthetics

  • 03.

    Smooths off sharp edges

  • 04.

    Improves resistance to fatigue

Process of aluminium electropolishing

The electropolishing process on aluminium involves the removal of a limited amount of material from the outer layer to eliminate surface imperfections, contaminants, sharp edges, burrs, cracks and micro-perforations that contribute to corroding the item. 

The surface that is obtained by electropolishing aluminium is smooth, highly resistant to corrosion and free from imperfections that could compromise the strength and longevity of the material.

Since 1996, Alticolor has been the trusted point of reference for companies in need of treatments on aluminum components.

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