Product Info

    The latest process for zinc/nickel alloy plating from an alkaline cyanide-free bath.


    Alkaline cyanide free zinc-iron alloy plating process producing deposits with 0.1% – 0.8% Fe. Iron content in solution is easily controlled and process does not require dual rectification.


    Next generation alkaline cyanide free zinc-nickel plating process. Provides a bright, ductile zinc-nickel deposit containing 12% – 15% Ni. Readily accepts clear, blue, black and high corrosion trivalent passivations.

    COLLOY NI-Z POSIT II Features & Benefits Sheet

  • COLLOY A-Z-N 300

    Latest generation acid zinc-nickel plating process that offers enhanced ductility and throwing power. Provides a level, mirror bright, ductile electro-deposited zinc-nickel alloy containing from 12% to 15% nickel that is evenly distributed at low, mid and high current densities. Process operates at lower, more economical temperatures, is free from boric acid and ammonium salts and ideal for use on castings or heat treated steel components.
