That information would be contained in the vendors technical data sheet. If you are not using a proprietary formulation then you need to experiment yourself.

HELLO SIR,
Generally alkaline zinc baths contains 10-15 percent of nickel and rest is zinc.

For good corrosion resistance, the higher the nickel conent up to 15%, the better. However if a post treatment such as a chromate, Hex or try chrome, is requirred 9 percent nickel is suggested. Higher nickel content makes it difficult to obtain a good resistant finish of the post treatment.
