Excellent protection against corrosion and maximum adhesion for subsequent finishes on items used in the aerospace and electromechanical industries.
Protection against corrosion
Clean surface
Guaranteed high electrical conductivity
Eliminates contamination from iron and other metals
Resistance to heat
Improved adhesion of surface paint
The passivation carried out by Alticolor is a trivalent chromium immersion process that gives the substrate increased protection against corrosion. The resulting conversion coatings are very thin, even less than 0.5 micron, and deliver a twofold action, protection against corrosion and support for the adhesion of organic finishes on the metal, using varnishes or paints.
The oxide layer obtained through the passivation of aluminium is slightly iridescent with blue-bronze hues. As metal conductivity remains unchanged, chromium passivation is a process that is particularly suited to products used in the electronic and military sectors.
Treatment carried out in compliance with standard MIL-DTL-5541F
Since 1996, Alticolor has been the trusted point of reference for companies in need of treatments on aluminum components.
A customer operating in the aerospace industry contacted Alticolor with the need to protect aircraft control panels from corrosion. A solution for this was passivation treatment, with particular focus on guaranteeing a current conducted in the treated item, to power the control panel instrumentation.
Alticolor treatments undergo rigorous control procedures
resulting in certification to guarantee the quality
of the process management.
