Datasheet: Monel® K-500

Monel® K-500

This Nickel-Copper alloy is precipitation hardenable, due to the additions of Aluminium and Titanium. It combines the corrosion resistance of Monel 400 but gives the added advantage of extra strength and hardness (as a result of its age hardening ability).

Monel® K-500 is also known as Nicorros Al.

Available in all profile options
