  • Differences between chloride (acid) and alkaline zinc plating

    Acid zinc is brighter, but alkaline zinc offers measurably better throwing power, which can be important for rack plated work. Acid zinc holds some disadvantages for the plating shop, like being very corrosive, while alkaline zinc has its requirements and quirks as well. Alkaline zinc is probably growing in popularity while acid zinc is waning.
