Monel K500/UNS N05500/2.4375 Monel Alloy With Good Mechanical Properties In Marine Applications
Monel K-500 is a high-strength, corrosion-resistant nickel-copper alloy that combines the properties of Monel 400 with additional strength and hardness, thanks to the inclusion of aluminum and titanium. It offers excellent resistance to seawater, chemicals, and high temperatures, making it ideal for challenging environments. The alloy is highly resistant to stress corrosion cracking, oxidation, and fatigue, ensuring long-lasting performance in demanding applications.
Monel K-500 maintains its strength and toughness at both low and high temperatures, making it suitable for industries such as aerospace, marine, and chemical processing. It is non-magnetic, a key advantage in sensitive applications. Additionally, Monel K-500 is known for its excellent fatigue resistance and fabricability, allowing for easy machining, welding, and forming.
Common uses include turbine blades, propeller shafts, valves, pumps, and fasteners in high-stress, corrosive, and high-temperature environments, particularly in aerospace, marine, oil & gas, and chemical industries.
