About Monel nickel-copper alloys
Monel is a nickel-copper alloy family with strong resistance to seawater, hydrofluoric acid, and reducing environments. Monel 400 is the general-purpose grade for marine and chemical service; K-500 adds aluminum and titanium for age-hardened high-strength applications.
