An alkaline zinc-nickel alloy electroplating process with a stable nickel content of 12-15% in the plating layer.
It produces zinc-nickel plating with stable alloy composition and uniform thickness across a wide current density range.
The zinc-nickel alloy plating has excellent corrosion resistance and high-temperature resistance, meeting the strict requirements of the automotive industry even after heat treatment (thermal shock).
It is suitable for barrel plating applications; for rack plating, choose Zhongdu Technology’s AZN-222 series products.
Its high cathode efficiency ensures fast plating speed, no burning in high current density areas, and increased output.
When used with Zhongdu Technology’s natural passivation, black passivation, and sealing products, the salt spray resistance is better.
It is the best choice for hexavalent chromium-free post-treatment, complying with the EU ELV and RoHS directives.
