Cobalt is shiny, grey, brittle metal with a close packed hexagonal (CPH) crystal structure at room temperature but which changes at 421Â°C to a face centred cubic form. The metal is rarely used as a structural material in the pure form but almost always as an alloy or a component of another system.
