Plating on Monel

Monel is a nickel based superalloy developed in 1905. Comprised of a blend of nickel, copper, titanium, aluminum, and iron, Monel is best known for its ability to maintain its great strength at drastically high temperatures. This high thermal resistance makes Monel a commonly used material in the Aerospace and Defense industries

Monel also possesses great chemical strength and is resistant to many levels of corrosion, especially corrosion from salt water and caustic chemical solutions. These chemical properties make Monel a formidable substrate choice in aqueous manufacturing.

Common Monel finishes include:

Despite being chemically engineered to outperform some of the top alloys on the market, superalloys like Monel also benefit greatly from a successful surface finish. Increased strength, thermal resistance, electrical conductivity, and corrosion resistance are all beneficial qualities that can be gained through certain metal finishing processes. Some common finishes for Monel substrates include:

  • Nickel
  • Nickel (as a base layer)
  • Gold 
  • Silver 
  • And more!

Benefits of Plating Monel

Superalloys alone possess great strength and chemical resistance; however, they are not perfect. Like any other metal alloy, Monel is susceptible to corrosion from prolonged exposure to certain environments. This is where choosing the appropriate surface finish is crucial. Some benefits of plating on Inconel Alloys include:

  • Increased Corrosion Resistance 
  • Improved Conductivity
  • Reduce Component Maintenance 
  • Provides a smooth, long-lasting, Aesthetically Pleasing Finish
  • And many more!

Monel also possesses great chemical strength and is resistant to many levels of corrosion, especially corrosion from salt water and caustic chemical solutions. These chemical properties make Monel a formidable substrate choice in aqueous manufacturing. 

What are Superalloys?
Monel is an incredibly unique material, that belongs to a family of man-made compositions called “Superalloys.” Like the name says, Superalloys are a sub-group of alloys that are designed to be incredibly strong, along with an abundance of other desirable physical and chemical properties. Superalloys are typically nickel-based, but cobalt-based and iron-based superalloys also exist. 

In the case of Monel, it was designed to resist high levels of corrosion and to perform in extreme temperature environments. Monel is very similar to its superalloy peer Inconel, except the major difference is that Monel is a copper-nickel alloy, while Inconel is a chrome-nickel alloy.
Why Plate Superalloys?

You may be thinking, “if these alloys were engineered to be chemically and physically stronger than normal alloys, why should I plate my superalloy components?” And while the first half of that statement is true, superalloys are much stronger than their non-super counter parts, they are still susceptible to corrosion, wear, and abrasion damage.  

Finding the right surface finish or electroplating solution for your superalloy substrates and components is essential to improving their functionality. Luckily AOTCO has 50 years of experience and a dedicated team of platers and engineers ready to find your superalloy surface finishing solution.

Common Industry Applications for Monel Substrates
Monel Alloys have an incredible ability to perform in high temperature environments for long periods of time, even getting stronger at certain temperatures. This makes Monel a good component material when manufacturing for high temperature environments. Some common industry applications of Inconel alloys include:
  • Jet engines
  • Exhaust pipes
  • Flare stacks
  • Aqueous Components 
  • And many more!
