Tantalum Metal and Tantalum Alloys

Tantalum is a shiny, silvery metal. Tantalum is soft when it is pure. At temperatures below 150°C, it's almost resistant to chemical attack. Thanks to an oxide film on its surface, t tantalum is virtually immune to corrosion.

Tantalum and Tantalum Alloys Applications

Tantalum is mainly used in four areas: high-temperature applications, like aircraft engines, electrical devices, like capacitors, and surgical implants, and handling corrosive chemicals. Tantalum resists corrosion and is nearly impervious to chemical attacks, for this reason, it's been employed in industry, e.g. for heat exchangers in boilers where strong acids are vaporized. Tantalum is rarely used as an alloying agent because it tends to form metals brittle.
