Alloy K500 is a nickel-copper alloy, precipitation hardenable through additions of aluminum and titanium. This alloy shows the corrosion resistant characteristics of grades such as Alloy 400 but with enhanced strength and hardness after precipitation hardening. However, it can be further strengthened by cold working before the precipitation hardening.
We supply Alloy K500 material in both the Cold worked and Hot Worked and Aged condition to offer the best combination of excellent mechanical properties from sub-zero temperatures up to about 480°C, together with very good corrosion resistance in both marine and chemical environments.
These properties, plus the fact that it is non-magnetic, make it eminently suitable for use as propeller and pump shafts, and pumps and valves components used in the manufacture of perchlorethylene, chlorinated plastics, and in marine applications where high strength and corrosion resistance are required.
