Monel® K500 (UNS N05500)

Nickel-Copper Alloy

Monel® K500 Nickel Alloy

Monel® K500 offers all the benefits of MonelĀ®400 but with greater strength and hardness.


The mechanical properties of the alloy are 3 to 4 times greater, achieved in part due to the inclusion of aluminium and titanium during the alloying process, which makes the material age-hardenable. Monel® K500 also offers the same, excellent corrosion-resistant qualities.

Delivery Condition

The delivery condition of the alloy includes annealed, age-hardened, hot-finished, or stress equalised. The product provides very high strength and hardness and high tensile properties up to 650°C (1200°F) after age-hardening. Good fatigue and corrosion fatigue resistance are also achievable after age-hardening.

Typical Applications

Commercial applications for this engineering material include:

  • Fasteners and springs
  • Pump and valve components
  • Oil well drill collars
  • Impellers
  • Marine engineering applications

We stock Monel® K500 in round bar and round tube.
