Tantalum (Ta) – Custom Machined Parts
Tantalum is characterized by its high density, extremely high melting point (3,017°C), and excellent corrosion resistance. Being extraordinarily resistant to heat, it is classified as a refractory metal.
In contrast to other refractory metals such as tungsten and molybdenum, production of tantalum often involves melting operation just like most industrial metals and alloys, which produces less material defects. Also, tantalum has good ductility and machinability compared to other refractory metals.
Despite all of these advantages of tantalum, however, applications are often limited to small parts/components due to its high cost.
