WHY ZINC PLATING?
- Substantially increased corrosion-resistant properties of the finish as a result from the alloying of nickel to the zinc in the deposit
- Out-performs regular zinc plating in corrosion resistance up to 10 times the atmospheric exposure
- Passivation treatments and top-coats also available to increase finish performance above and beyond the most stringent requirements
Zinc is a metallic chemical element commonly found in the earth’s crust. In its natural state, zinc has a shiny, bluish-white appearance, although commercial-grade zinc is more of a dull gray in color. Zinc is a hard, brittle metal but becomes more pliable when exposed to extreme heat.
ZINC IN ELECTROPLATING
Zinc is a popular choice for industrial plating due to its excellent corrosion protection properties and the fact that it is relatively inexpensive. The use of passivation treatments or the alloying of zinc with other metals such as nickel, cobalt, or iron can enhance zinc’s corrosion resistance. When plating with zinc, thoroughly cleaning the surface is essential for removing rust or other materials that can prevent adhesion. This can be accomplished by using an alkaline detergent and then treating the surface with acid.
