Cobalt is a transition metal found between iron and nickel on the periodic table. It has a high melting point (1493°C) and retains its strength to a high temperature. Similar to iron or nickel, cobalt is ferromagnetic. It can retain its magnetic properties to 1100°C, a higher temperature than any other material. Ferromagnetism is the strongest type of magneticism:
It’s the only one that typically creates forces strong enough to be felt, and is responsible for the magnets encountered in everyday life. These unique properties make the metal perfect for two specialized high-tech purposes: superalloys and battery cathodes.
