Tantalum is a rare metal with a steel gray luster, a melting point of 2980°C and a density of 16.6 g/cm 3. Tantalum is a very stable chemical element with similar properties to niobium. Tantalum is ductile and can be drawn into fine wire or made into thin foil. Its coefficient of thermal expansion is very small, expanding by only 6.6 parts per million per degree Celsius. In addition, it is very ductile, more so than copper.
