FAQ: Frequently asked questions about our coated wire
-
Copper-plated, zinc-phosphated and soap-coated, polymer-coated, continuously oiled, phosphate-free.
-
Yes, phosphate-free coatings are being actively developed and offered.
-
Classic phosphate coating is based on zinc phosphate and offers good formability and corrosion protection.
Phosphate-free coatings, on the other hand, do not use phosphate and rely on alternative systems such as polymer coatings or continuously oiled surfaces - they are more environmentally friendly and reduce the effort required for further processing.
-
The trend toward phosphate-free coatings is driven by sustainability goals, cost savings, and process simplification. Phosphate-free systems eliminate the need for costly washing processes for dephosphatization, reduce environmental impact, and enable more efficient production.
-
-
De-phosphating is an additional process step that is necessary for phosphated wires in order to remove residues – this causes costs and environmental pollution.
-
Hydrogen formation can occur during phosphating and lead to hydrogen embrittlement, which poses a risk to component safety.
-
δ-ferrite formation affects the microstructure of the material and can have a negative impact on mechanical properties
Phosphate-free coatings minimize these risks and improve process reliability.
-
-
Uniform layer thicknesses across the entire wire core – individually adjustable.
-
Polymer coatings and optimized zinc phosphating offer excellent formability.
