FeNi is an iron-nickel alloy combining the strength and affordability of iron with nickel's corrosion resistance and toughness. This binary system is widely used in aerospace, marine, and automotive applications where moderate strength coupled with environmental durability is required, as well as in precision instruments and magnetic applications where the iron-nickel composition provides controlled electromagnetic properties. Engineers select FeNi alloys when a balance of cost-effectiveness, fabricability, and corrosion resistance is needed—particularly in saltwater exposure or chemically aggressive environments where pure iron would degrade but premium stainless steels would be overspecified.
