Monel K500 is an advanced NiCu alloy that combines desirable characteristics such as high corrosion resistance, strength and toughness. It contains a significant amount of nickel (roughly two-thirds), with the balance being copper plus other elements like iron, manganese, carbon and silicon. These additional elements improve the metal's physical properties, making it highly resistant to stress corrosion cracking in an aggressive environment while maintaining its flexibility at a wide range of temperatures.

Monel K500 is a nickel-copper alloy with strength and corrosion resistance in extreme conditions. It has a high yield strength, excellent strength and flexibility, good weldability and machinability, and superior mechanical properties in both the annealed and solution-treated conditions. Monel K500 also offers excellent corrosion resistance to fresh water and seawater and to many corrosive acids such as hydrochloric acid, sulfuric acid, phosphoric acid, nitric acid, etc. Its most commonly used applications include marine components like propellers & impellers due to their resistance against saltwater corrosion.
