Alkaline non-cyanide zinc (ANCZ) plating has been prevalent in the plating industry for about 50 years. It has become a preferred process for finishers who require a fairly bright zinc-plated finish on parts that have challenging geometrical shapes. ANCZ is typically the chosen zinc process for complicated geometrical shapes due to its ability to plate zinc at a preferred low ratio of zinc thickness from the high current density areas to the low current density areas. Thickness ratios can range anywhere from 1:1 to 2:1 from the high current density area to the low current density area. Bath … [Read more...]
