Cobalt (Co) is a ferromagnetic transition metal known for its high strength, excellent wear resistance, and superior performance at elevated temperatures. It is widely used in superalloys, magnetic applications, and wear-resistant coatings where conventional steels cannot survive extreme conditions. Engineers select cobalt-based materials for demanding aerospace and industrial applications where thermal stability, fatigue resistance, and corrosion resistance are critical, though cost and density are considerations relative to alternatives like nickel-based systems.
