Zinc

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. SPC Does not provide hexavalent chromate/passivate (i.e. yellow chromate)

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.

For Zinc Coating

Applications

Zinc plating is ideal for use with nuts, bolts and metal brackets as it produces a smooth, clean finish and slows the onset of rusting and other corrosive processes. Zinc plating is also frequently used to provide an undercoating on surfaces prior to painting. Zinc and zinc alloys have been used in the automotive industry for many years on engine parts, brake components and power steering components. Other uses include heavy electrical transmission components, fasteners and in the manufacturing of tanks and armored personnel carriers in the defense industry.

Zinc plating is not recommended for use in the manufacturing of spot-welded, riveted or assembled parts, as these can trap harmful chemicals during the plating process.
