suitable for aerospace and marine

accessories, automotive accessories

electroplated zinc nickel alloy with high

corrosion resistance requirements.

  SGS product


passivation film



Fast deposition

Using the new technology independently

developed by Bigely, the deposition speed

is 50% faster than the traditional process,

effectively increasing the production



Good dispersion ability

It is prepared with high-quality raw

materials from BASF, and its dispersion

ability is improved by about 35%

compared with the traditional process.

Suitable for hanging plating multi - Angle

deep concave complex parts and rolling

plating deep hole workpiece.

  Excellent corrosion


temperature resistance

Nickel content is

uniform and stable


Regardless of the current density from

small to large, from the opening of the

bath to long-term use, the nickel content

of the coating is uniformly stable at

12-15%, easy to manage and easy to



Low organic



The plating solution has high stability and

is not easy to aging, which can reduce the processing time and the loss of chemical

raw materials.



High tolerance




consumption is low,

durable and affordable
