Inconel and Monel

Both Inconel an monel are Nickel-based alloy metals. Where the main elements contained in this metal are Nickel elements. Unlike steel, steel is a metal alloy based on Fe-Ni metal elements. then what is the difference between monel and inconel?

The fundamental difference

Both Monel and Inconel have nickel as their primary metal. However, Monel has copper and Inconel has Chromium. Monel is a nickel-copper (Ni-Cu) alloy and Inconel is a nickel-chromium (Ni-Cr) alloy.

To better distinguish the difference between these two, we need to address the strength of their dual-primary ingredient.

The Difference Between Nickel-Copper and Nickel-Chromium

Nickel Chromium (Inconel)

Nickel and chromium together are fantastic at fending off oxidation and high-temperature corrosion. This would make them ideal for places that interact with frequently different gasses and large temperature variances.

Nickel Copper (Monel)

Nickel Copper, however, is great for corrosion resistance. Their notable strengths would be against sea water, both hydrofluoric and sulfuric acids, as well as alkalies and harsher acids.

Monel, is an alloy of nickel (Ni = 67%) with copper metal (Cu = 28%) and other metal elements ferro, Mn, and Si. The use of monel metal is much for the chemical industry, food ingredients due to its excellent corrosion-resistant properties in addition to its strength and tenacity and high temperature resistance. The monel metal can withstand physical and mechanical properties up to a working temperature of 750 ° C.

Alternate Characteristics

Regardless of heat transference and corrosion resistance, there are other factors that will affect your purchase of either.

Inconel, on average, tends to have higher yields and tensile strength. This will tend to make it greater as a structural product if you are looking to use it in chemical plants.

Additionally, while we wrote about how Monel is better when dealing with sea water and corrosion resistance, it is worth noting that Inconel 625 specifically does particularly well at resisting sea water and marine conditions, in the chance you are looking for a happy medium.

Properties and Characteristics of Monel

1. Resistance to deterioration makes Monel 400 ideal for use in equipment parts that remain in chemical and marine environments .
2. For producing hydrocarbon and chemical processing equipment .
3. In carburetor needle valves and sleeves, exhaust manifolds and other critical parts of aircraft .
4. Making screw machine products, heat exchangers, piping systems and wind instruments .

That’s the difference between monel and inconel, so we can know the difference and can choose material according to the application, function and purpose
