Zinc/nickel surface treatment
With a zinc-nickel surface treatment, Hydynamic offers you the best coating currently available in the field of cathodic corrosion protection for steel. The galvanically applied zinc-nickel alloy, consisting of 12 to 15% nickel, has proven itself especially in applications where extremely high corrosion resistance is required.
Zinc-nickel coatings are used when traditional electrolytic galvanizing does not meet life-time requirements, for example due to exposure to high temperatures or aggressive environmental conditions. In recent years, this technology has undergone significant developments to meet the increasingly stringent standards of the automotive industry. Today, more and more companies in a variety of industries are making the switch to zinc-nickel coatings because of their superior corrosion protection.
