Introduction
Monel K-500 (UNS N05500/ W.Nr. 2.4375) is a nickel-copper alloy which combines the excellent
corrosion resistance of MONEL alloy 400 with the added advantages of greater strength and hardness. The
increased properties are obtained by adding aluminum and titanium to the nickel-copper base, and by heating
under controlled conditions so that submicroscopic particles of Ni3 (Ti, Al) are precipitated throughout the
matrix. The thermal processing used to effect precipitation is commonly called age hardening or
aging.
Typical Uses and Applications
Monel K-500 products are widely used for chains and cables, fasteners and springs for
marine service; valve components for chemical processing; scrapers for pulp processing in paper production; oil well drill collars and instruments, pump shafts and impellers, non-magnetic housings, safety lifts and valves for oil and gas production; sensors and other electronic components.
