Acosur® ZNA
Acosur® ZNA

Components for landing gears

Acosur ZNA for fasteners, which are exposed to corrosion, as a substitute for cadmium coatings in the landing gear area.

Spherical plain bearings

Excellent corrosion resistance and high adhesion to stainless steels make Acosur ZNA the ideal replacement for cadmium coatings.

Did you know ?

The cadmium replacement for Aerospace

Acosur® ZNA is a modified electroplated zinc-nickel alloy coating. It is characterized by excellent adhesion and high corrosion protection and also meets the requirements of Airbus AIPS 02-04-006, AMS 2417 as well as prEN 4826.

Thus, Acosur ZNA is a contemporary substitute for conventional aerospace anti-corrosion coatings like cadmium or chromium VI-containing zinc coatings.


The ability to coat even high alloy stainless steels and materials, combined with a layer thickness of 1-3 microns, makes Acosur ZNA inter alia, the ideal coating process for bearing components.

Designed for versatile use

A wide range of layer thicknesses and the possibility to coat high-alloy steels guarantee a wide range of applications.


Bearing parts

Thin films and very high corrosion protection make Acosur ZNA the ideal replacement for cadmium coatings on bearing components.


  1. not acid-resistant

  2. resistant to lubricants, fuels and solvents
