Monel Industry Information


Monel is a registered trademark that encompasses a series of nickel-copper alloys. With a range of alloys, including Monel 400, 401, 404, K-500, and R-405, Monel is often used in applications requiring a high degree of corrosion resistance as well as moderate heat resistance. In addition to nickel and copper, Monel alloys often include trace amounts of iron, manganese, carbon, and sulphur.

Applications of Monel Alloys

Characteristics of Monel alloys include high strength, high malleability, low coefficient of thermal expansion, and excellent sanitation.

Monel alloys are often used in these industries:

For seawater valves, strainer baskets, trolling wire and various fixtures and fasteners.
For gasoline tanks, off-shore oil rigs, petroleum stills, and varied processing equipment.
For instruments including trumpets, French horns, and tubas, and accessories such as bass guitar strings.
For use in household fixtures, such as kitchen sinks and interior décor, such as doorknobs and decorative screens.
Industrial Manufacturing
For use in boilers, chemical tanks, and various stock such as tubes, wire, sheet, and plate used in manufacturing equipment and parts.
Monel 405
Is mainly used in marine, oil, and chemical industries. It can also be used in heat exchangers, alkylation plants, brine heaters, steam generator tubing, pickling bat heating coils, and monoethanolamine reboiling tubes.

Material Properties of Monel Alloys

The basic composition of Monel is 65-70% nickel, 20-29% copper, 5% manganese, and small percentages of iron and other elements.

The various Monel alloys differ slightly in terms of composition:

Monel 400
Composed of 63% nickel, 28-34% copper, 2.5% iron, 2% manganese and small amounts of sulphur, carbon, and silicone.
Monel 404
Composed of 52-57% nickel, 2% iron, 45% copper and small amounts of aluminum, manganese, silicone, carbon, and sulfur.
Monel K-500
Composed of 64% nickel, 30% copper, 1% iron, 2.8% aluminum and small amounts of carbon, titanium, and manganese.

Benefits of Using Monel Alloys

The varied chemical compositions make the Monel alloys well-suited for specific tasks. For example, Monel 404 is often used in the electronics industry because of its low permeability, while Monel K-500 is ideal for marine equipment applications because of its high resistance to corrosive seawater elements.

Monel 405 is resistant to steam at high temperatures as well as sea water. It's also resistant to caustic and salt solutions. It provides superior corrosion resistance in a wide range of media. It is characterized by relatively moderate-to-high strength, combined with good corrosion resistance. It is resistant to both hydrofluoric and hydrochloric acids. It is slightly magnetic at room temperatures.

Points to Consider When Purchasing Monel Alloys

Although Monel alloys are malleable, they can be difficult to machine because they tend to harden instantly in response to heat. As a result, Monel alloys must be turned while machining at slow speeds and with low feed rates. Thus, when being machined, Monel alloys are typically forged using an open die forging technique.

Monel is often manufactured to standards set by the American Society for Testing and Materials (ASTM) or the American Society of Mechanical Engineers (ASME).
