... metals have this property (Fe, Ni, Co), but cobalt has it best. Its curie point (the point when a ferromagnetic metal loses its ferromagnetism) is 610 °C (1130 °F); this is much higher than that of steel, 410 °C (770 °F), and nickel, 181 °C (358 °F). This property makes cobalt useful for high-temperature...
