It can be found in certain ores with other metals such as nickel, copper or arsenic. It has high melting and boiling points, approximately 1,500°C and 3,000°C, respectively. Cobalt has elemental, organic, and inorganic forms. When combined with tungsten carbide, the material is termed "hard metal" and is used for industrial cutting, drilling, and polishing. Cobalt is also found in jewelry alloys and has ferromagnetic properties making it a useful component in magnets.
