Cadmium Plating

Cadmium Plating Services for Advanced Manufacturers

Cadmium plating is the process of applying a thin layer of cadmium to an object’s surface in order to provide it with the chemical and physical properties of the element. It provides a sleek, aesthetically pleasing blue-grey finish to its substrates and provides them with a long-lasting and corrosion resistant coating.

Cadmium itself is a highly malleable, soft, silver metal that when applied to a substrate’s surface creates a ‘sacrificial coating.’ This means that the cadmium applied will corrode entirely before any of the lower-layered metals get damaged.

This coating makes Cadmium plating an unrivaled finish when seeking corrosion protection. It’s resistance to corrosion, along with a multitude of other benefits, are why cadmium plating is so common in Aerospace and Defense manufacturing

Benefits of Cadmium Plating

The incredibly unique chemical qualities of Cadmium make it an excellent deposit when looking to combat corrosion. Aside from increasing corrosion resistance, Cadmium plating can provide its substrates with a wide range of chemical and physical properties. Some of the most notable benefits of Cadmium plating are:

  • Corrosion Resistance
  • Solderability
  • Good conductivity
  • Adhesive
  • Malleable
  • Highly Ductile
  • And more!

Frequently Asked Questions

Common Substrates for Cadmium Plating

Cadmium plating is nearly unparalleled in its ability to resist corrosion, and therefore it is typically paired with metals that are more susceptible to corrosion and oxidation. Steel, Iron and their respective alloys are frequently coated in Cadmium to bolster the chemical strength of their surface. Some of the most common substrates for Cadmium plating include:

  • Steel
  • Brass
  • Iron and Other Ferrous Alloys
  • Bronze 
  • Copper
  • And more!
Special Note

While Cadmium is a very common and effective metal finish, it is worth noting that the substance is considered to be toxic and can be dangerous if not handled properly and within the set regulated limits. Luckily, at AOTCO, our team provides up to 50 years of expertise working with Cadmium (as well as an array of other materials) and are well prepared to aid in your next Cadmium plating job.

Other elements to consider before submitting a Cadmium plating purchase order are coating requirements, specification requirements, and any pre and post process treatments that will be required.
