Palladium Plating

Palladium plating is an electroplating process that uses an electrical current and a chemical bath solution to apply palladium ions to the surface of an object or substrate. Once applied, the substrate gains an array of desirable chemical and physical properties.

Benefits of Palladium Plating

While Palladium is expensive, the benefits of plating with the strong precious metal cannot be overlooked. Maybe the most notable quality of Palladium is its ability to act as a catalyst, converting harmful emissions like carbon monoxide and nitrogen oxide into more benign compounds. Some of the most notable benefits of palladium plating are as follows:

  • Corrosion Resistance
  • Increased Strength
  • Abrasion / Wear Resistance 
  • Adjustable Electrical Conductivity
  • Aesthetically Pleasing, long-lasting finish
  • And many more!

Industrial Uses for Palladium Plating

Due to its ability to act as a catalyst, the most common and notable industry use of Palladium and Palladium plating is within catalytic converters in the automotive industry. Since palladium can convert carbon emissions into less harmful compounds, it is a staple in most automobile catalytic converters. Aside from that, there is still a wide range of industry application for palladium plating. Some of the most notable uses for palladium plating include: 

  • Automobile Components (catalytic converters)
  • Dental implants (crowns, inlays, bridges)
  • Electronic Devices (phones, laptops, tablets)
  • Jewelry 
  • And many more!

Frequently Asked Questions


Originally discovered in 18th-century Brazil and deemed “Oruo Podre” or “Worthless Gold”, Palladium, and its full list of chemical and physical properties, weren’t officially documented until the early 1800’s when UK scientist William Wollaston was experimenting with Platinum. Named after recently discovered asteroid at the time “Pallas”, Palladium has seen continued use to this day, throughout a wide range of manufacturing industries.

Palladium is a precious metal that is stronger than gold, and more expensive per ounce. While the material was once more abundant and even seen as a cost-effective alternative for gold plating, the abundance of Palladium has been unable to keep up with industry demand and the material has become very expensive in recent years.

Common Substrates for Palladium Plating
Like most other precious metals, Palladium can be deposited on the surface of any substrate with little issue. Due to its wide range of industry uses, the list of common palladium-plated substrates is extensive. Some of the most common substrates for palladium plating are as follows:
  • Silver
  • Gold
  • Steel
  • Bronze
  • Brass
  • And many more!
Please Note: In recent years Palladium prices have skyrocketed, making it one of the most expensive plating deposits available in the industry. If you are looking for a similar yet slightly more cost effective option, AOTCO also offers Rhodium and Gold plating services as well.
