Monel K-500 Nickel Alloy

The Monel K-500 nickel alloy has the same corrosion resistance as the Monel 400 but higher mechanical strength and hardness. The strengthened properties are achieved by the additions of aluminum and titanium to the nickel-copper base and by heating under controlled conditions. Monel alloy K-500 also has excellent resistance to high temperature corrosion and long term structure stability.

Typical applications for this nickel-copper super alloy and its products are turbine blades and gas turbine blades for aircraft engine, fasteners and springs for marine services, pump and valve components for chemical processing, doctor blades and scrapers for pulp processing in paper production, etc.
