Monel K-500 Filler Wire, commonly designated as ERNiCu-7 (for welding Monel alloys) or UNS N05500, is a precipitation-hardenable nickel-copper alloy welding wire widely used for welding Monel alloys and other nickel-based materials that require excellent corrosion resistance and high strength.
Monel K-500 is similar in composition to Monel 400 but contains additional aluminum and titanium, which allow the alloy to be strengthened through precipitation hardening. This results in significantly improved strength, hardness, and wear resistance while maintaining excellent corrosion resistance.
Monel K-500 filler wire provides exceptional resistance to seawater corrosion, acidic environments, and chloride-induced stress corrosion cracking. It is widely used for welding components used in marine, offshore oil and gas, chemical processing, and aerospace industries.
Due to its high strength and corrosion resistance, Monel K-500 filler wire is commonly used for welding marine propeller shafts, pump components, fasteners, and offshore equipment.
