16Ni-7Co Maraging Steel

16Ni-7Co maraging steel is an iron-nickel-cobalt age-hardening alloy engineered to achieve ultra-high strength through precipitation hardening rather than carbon content, making it exceptionally strong yet tough and weldable. Used primarily in aerospace, defense, and precision tooling applications where weight reduction and extreme strength are critical, this material excels in environments requiring both high performance and fabrication flexibility—notably in missile casings, landing gear components, and high-strength fasteners where conventional high-carbon steels would be brittle. Its combination of hardness, fracture toughness, and machinability makes it a preferred alternative to conventional tool steels and superalloys when weight and damage tolerance matter as much as ultimate strength.
