Monel K500 (Alloy K-500, UNS N05500,2.4375)

Monel K500 (Alloy K500) is a nickel-copper alloy. Monel K500 is made of aluminum and titanium. Monel 400 has higher corrosion resistance than the corrosion resistance, but also has higher strength and can be cured according to Monel 400. This requires the use of the Monel K500 in applications that require higher corrosion resistance and hardening of the material.
