Zn-215 produces about 10%-15% nickel of zinc-nickel alloy layer in original acid zinc salt electrolyte.

Zn-215 layer can passivate directly, the resistance of corrosion better than zinc or other zinc basic alloy plate.

Zn-215 alloy solution has a wide current density and stable nickel eutectoid rate.

Zn-215 has good throwing power and covering power, the corrosion to equipment is small. Zn-215 is suit for barrel and rack plating.
