Zinc-Iron (ZnFe)

CORROSION PROTECTION WITH ZINC AND IRON

Electrolytic zinc-iron is an electrolytic coating process that deposits a layer of zinc and iron on a metal substrate. The resulting alloy offers superior corrosion resistance to traditional zinc coatings, making it an ideal choice for applications that require high levels of protection against environmental factors such as moisture, salt and chemicals.

Here are some typical specifications that can be achieved with zinc-iron plating:

  • Corrosion resistance of at least 360 hours in salt spray tests to ISO 9227 or ASTM B117.
  • Coating thickness of 5 to 15 micrometres.
  • Uniform coating coverage with minimal porosity and excellent adhesion to substrate.
  • Excellent weldability and processability of the coated substrate.
  • The coating can be applied to a variety of metals, including iron, steel, cast iron, Zamac and copper.
  • Finished in matt black or brilliant blue-white.
  • Cost effective

Complete coating

A layer of electrolytically applied ZnFe considerably improves the appearance, resulting in a higher product value and greatly improved corrosion resistance. After a 360-hour salt spray test, the material shows a maximum of 5% white rust (DIN 50021). The applied coating is UV-resistant, making it an excellent choice for outdoor applications.
