• Yellow Zinc – This type of zinc coating is commonly used in the automotive industry and offers an average level of protection against corrosion.
• Black Zinc – Black zinc coatings are available as a black oxide that can actually be olive-drab in color, or as a pure black coating. The former will normally provide slightly better corrosion resistance.
• Clear or Blue Zinc – This coating formulation tends to offer fewer amounts of corrosion protection, although it’s regarded as being more environmentally friendly.
• Acid Zinc – Acid zinc plating differs from other types of zinc plating, as it does not introduce cyanide into the plating bath. A key advantage of acid zinc is that it can be effective for use on hard-to-plate substrates.
