About Monel K500
Monel K500 is a nickel-copper alloy which combines the excellent corrosion resistance of Monel 400 (link) with the added advantages of greater strength and hardness. The increased properties are obtained by adding aluminum and titanium to the nickel-copper base, and by heating under controlled conditions so that submicroscopic particles of Ni3 (Ti, Al) are precipitated throughout the matrix. This is commonly called age hardening or aging.
The composition of Monel K500 alloy is given below.

Applications of Monel® alloy K500
Monel can be used in a variety of high temperature and corrosive environments. Some applications of Monel K500 include marine engineering, heat exchangers, valves, pumps, shafts, fittings, fasteners, and chemical processing equipment.
Here is a summarized list of potential applications for Monel K500:
- Chains and cables, fasteners and springs for marine service
- Pump and valve components for chemical processing
- Doctor blades and scrapers for pulp processing in paper production
- Oil well drill collars and instruments, pump shafts and impellers, non-magnetic housings, safety lifts and valves for oil and gas production
- Sensors and other electronic components
- Metal instruments and eyeglass frames
Monel K500 Mechanical Properties
Monel K500 has been found to have excellent dimensional stability, both in long-time exposure tests and in cyclic tests. This property of Monel K500 has led to its use in high-precision devices, such as gyros. Monel K500 alloy has been found to have exceptional mechanical properties from temperatures below zero to 480 degrees C (896 F).
Characteristics of Monel K500
Is Monel magnetic?
No, Monel K500 is virtually nonmagnetic, even at low temperatures. It is possible, however, to develop a magnetic layer on the surface of the Monel K500 during processing.
Aluminum and copper may be selectively oxidized during heating, leaving a magnetic nickel-rich film on the outside of the metal. The effect is particularly noticeable on thin wire or strips where there is a high ratio of surface to weight.
The magnetic film can be removed by pickling or bright dipping in acid, and the nonmagnetic properties of the material will be restored.
The combination of low magnetic permeability, high strength and notable corrosion resistance gives this alloy an advantage for use in a number of applications, notably oil-well surveying equipment and electronic components.
Is Monel corrosion resistant?
Yes, Monel K500 is highly resistant to corrosion and acids. The corrosion resistance of Monel K500 is substantially equivalent to that of alloy 400 (link) except that, when in the age-hardened condition, Monel K500 has a greater tendency toward stress-corrosion cracking in some environments.
Monel K500 has been found to be resistant to a sour-gas environment. The combination of very low corrosion rates in high velocity seawater and high strength make Monel K500 particularly suitable for centrifugal pumps shafts in marine service. In stagnant or slow-moving sea water, fouling may occur followed by pitting. However, this pitting slows down after a fairly rapid initial attack.
What is the difference between Monel and Inconel?
The composition of Monel and Inconel (link) varies, despite both metals being preferable for conditions with high temperatures, corrosive environments, and broadly severe conditions. Monel is a nickel-copper alloy, and Inconel (link) is a nickel-chromium alloy.
Monel is an excellent choice for saltwater applications, chemical processing machinery, crude petroleum stills, and more. Inconel metal alloys such as Inconel 600 (link) are preferable for oil and gas extraction, such as drilling. For more information, get in touch with our sales department.
Is Monel ferrous or nonferrous?
Nickel alloys like Monel are non-ferrous metals, meaning they have exceptional strength and corrosion resistance. Non-ferrous metals are also excellent for high-temperature applications. Monel’s non-ferrous properties make it a suitable choice for marine applications such as deep-sea mining, where seawater poses the threat of corrosion.
