The ductile (High Ductility) Zinc Nickel process is applied in a (bass) drum and (static) frame system with average thicknesses of 8 microns in transparent, silver, grey, blue, and black finishes, all of them exempt of Cr VI.
Its features are identical to those of conventional Zinc Nickel, adding properties of ductility and maximum flexibility, thanks to the modification of its micro-crystalline structures and their size.
The main advantage of this process is the fact that the possible bending and forming of workpieces may be done after the coating process.
Hydraulic, oil, fuel, water, and air pipes and other types of applications may be treated in the stage prior to bending, achieving significant reduction of costs and manipulation.
Another type of components, which require an operation of subsequent forming, stapling, folding, flanging, or flattening are also likely to be coated with this finish without damaging the coating and keeping intact the anti-corrosive properties, even in the areas of deformation, by not causing any detachment of the metal deposited.
At the same time the life cycle of the tools of bending or folding is increased due to their non-abrasion and zero particle detachment.
This coating respects European Directive 2003/EC/53 and RoHS,
Applications
Applications for automotive components that need to be processed with final mechanical operations once they are coated.
