MONEL®alloy 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 Ni 3 (Ti, Al) are precipitated

throughout the matrix. The thermal processing used to effect precipitation is commonly called age hardening oraging. The composition of the alloy is given in Table 1. Typical applications for MONEL alloy K-500
products are chains and cables, fasteners and springs for marine service; pump and valve components for
chemical processing; doctor blades and 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; and sensors and other electronic components.
