Introduction:
Monel alloy generally refers to nickel alloy, a heavy non-ferrous metal material composed of nickel as the base and other alloying elements. In order to further improve the physical and chemical properties of nickel and meet the requirements of scientific, technological, and industrial development, it is necessary to add an appropriate amount of alloy elements to nickel.
Monel products come in several different grades, each with specific chemical composition and mechanical properties. The following are several common Monel grades and their applications:
Monel 400 (UNS N04400): Monel 400 is a copper nickel alloy with excellent corrosion resistance and mechanical properties. It is widely used in fields such as marine engineering, chemical equipment, petrochemical equipment, seawater desalination devices, etc.
Monel K-500 (UNS N05500): Monel K-500 is a copper nickel alloy containing aluminum and titanium, which has higher strength and wear resistance. It is widely used in marine environments, pump valve manufacturing, centrifuge parts, and other fields.
Monel R-405: Monel R-405 is a sulfide reinforced copper nickel alloy with excellent toughness and corrosion resistance. It is commonly used for manufacturing bolts, nuts, and fasteners.

Monel 404 (UNS N04404): Monel 404 is a carbon containing copper nickel alloy with high strength and oxidation resistance. It is suitable for petrochemical equipment, aviation engine parts, etc. in high-temperature environments.
