FAQs about Monel k500(UNS N05500)

Monel K500 is a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance characteristic of Monel 400 with the added benefits of greater strength and hardness. It contains nickel (about 63%), copper (approximately 29%), and small amounts of iron and other elements. Due to its unique properties, Monel K500 is often used in marine applications, chemical processing equipment, and oil and gas industry components.

Monel K500 is typically supplied in the annealed condition. For optimum strength and hardness, it can be strengthened through a precipitation-hardening heat treatment process. The typical heat treatment involves solution annealing at temperatures between 870°C to 1040°C (1600°F to 1900°F), followed by aging at temperatures between 480°C to 595°C (900°F to 1100°F). This process results in the precipitation of intermetallic compounds, enhancing the alloy’s mechanical properties.

The density of Monel K500 is approximately 8.44 g/cm³ (0.305 lb/in³).

  • Monel K500: Primarily a nickel-copper alloy, Monel K500 offers excellent corrosion resistance, especially in marine environments. It exhibits good strength and hardness due to its precipitation-hardening capability. It is commonly used in marine applications, chemical processing, and oil and gas industry components.

  • Inconel 718: Inconel 718 is a nickel-based superalloy known for its high strength, excellent mechanical properties at elevated temperatures, and good corrosion resistance. It contains significant amounts of nickel, chromium, and molybdenum, along with other alloying elements. Inconel 718 is widely used in aerospace, automotive, and nuclear industries due to its exceptional performance under extreme conditions.

  • Monel K500 exhibits excellent corrosion resistance, particularly in marine and chemical environments. It resists corrosion from a variety of sources, including seawater, saltwater, and various acidic and alkaline solutions. While Monel K500 is highly resistant to corrosion, it is not entirely immune. Prolonged exposure to harsh conditions can lead to surface oxidation or discoloration, but it does not rust in the way that ferrous metals do.

  • Monel K500 is non-magnetic in both the annealed and hardened conditions, making it suitable for applications where magnetic properties are undesirable. This non-magnetic characteristic is due to its high nickel content, which imparts non-ferromagnetic properties to the alloy.


In conclusion, Monel K500 is a superior alloy offering a combination of corrosion resistance, strength, and non-magnetic properties, making it ideal for a wide range of demanding applications across various industries.
